* fix(promql): apply offset to subquery evaluation window (#9364)

* fix(promql): apply offset to subquery evaluation window

`prom_subquery_expr_to_plan` destructured `SubqueryExpr` without reading
`offset`, so `<subquery>[range:step] offset <d>` planned exactly the same
window as the un-offset form and silently returned data for the wrong time
range. The plain vector/matrix-selector paths already threaded the offset
through `selector_to_series_normalize_plan` and `RangeManipulate`.

Shift the inner evaluation window back by the offset and pass the offset to
the subquery's `RangeManipulate`, which maps the inner samples forward onto
the evaluation timeline before bucketing them into ranges. This matches
Prometheus, whose `evaluator.subqueryTimeRange` evaluates the inner
expression over `(start - offset - range, end - offset]` and whose
`evalSubquery` then hands the samples to the outer range-vector function as
a `MatrixSelector` that still carries the subquery offset. An offset on the
inner selector composes additively, as `subqueryTimes` documents.

`RangeManipulate`'s protobuf message has no offset field and recovers it on
decode from an immediately underlying `SeriesNormalize`. Since
`RangeManipulate` is commutative in `dist_plan` and can be pushed below a
`MergeScan`, insert that carrier node so the offset survives distributed
planning instead of decoding as zero.

Known divergence, unchanged by this commit: Prometheus anchors subquery step
points on absolute epoch multiples of the step, while GreptimeDB anchors them
on the evaluation start. The two agree whenever the offset is a multiple of
the subquery step; the added sqlness cases stay within that range.

Closes #9330

* docs(promql): correct the subquery-offset rationale and pin the histogram shift

Follow-up to e132c267, which stated two things inaccurately and left one
path untested. No behaviour change beyond a conditional clone.

The `SeriesNormalize` carrier was described as existing "so the offset
survives distributed planning", implying standalone is unaffected. That is
wrong. `local_offset` is read on the substrait decode path
(`range_manipulate.rs`, `instant_manipulate.rs`), and GreptimeDB routes
PromQL plans through `MergeScan`/substrait in standalone too -- the
standalone results `promql/encode_substrait.result` and `precisions.result`
both show `MergeScan [is_placeholder=false, remote_input=[...]]`. Deleting
the carrier therefore empties subquery-with-offset results in standalone as
well, while `count_over_time_subquery_with_offset` keeps passing because it
asserts the pre-serialization plan. Say so at the node, so the next reader
does not remove it believing standalone is safe.

The carrier is also not semantically inert: `SeriesNormalizeStream::normalize`
shifts native histogram `start_timestamp` payloads by `offset`. On the
subquery path that runs on a computed inner result, on top of any offset the
inner selector already applied, and nothing pinned it. It is consistent --
`RangeManipulate` moves the millisecond time index forward by the same
`offset_ms` -- so the distance from a histogram's start timestamp to the
sample carrying it, which reset/rate detection reads, is invariant. Add
`subquery_offset_shifts_histogram_start_and_time_index_together`, which
executes the subquery's node stack over native histogram samples for a
zero and a non-zero inner offset. It cannot be a sqlness case: native
histograms are a struct column with no SQL type or literal
(`sql_data_type_to_concrete_data_type` rejects structs) and the sqlness
runner speaks only MySQL/Postgres, so such rows only arrive over
gRPC/remote-write v2.

The divergence note blamed sub-step offsets. Measured, that condition is too
narrow: an unaligned evaluation timestamp alone diverges, with no offset at
all -- `sum_over_time(fine[20s:10s])` at t=57 samples 47s and 57s here
against Prometheus's 40s and 50s. The real condition is that
`(start - offset)` is not a multiple of the subquery step, and it is
pre-existing: the committed `tql eval (359, 359, '1s')
sum_over_time(metric_total[60s:10s])` case is already an instance of it
(`359 - 60 + 10 = 309`). Reword the comment and the sqlness header
accordingly. A sub-step offset stays accepted: `foo[20s:10s] offset 5s` is
valid PromQL, erroring on it would be a regression and would not close the
gap anyway. This repo has no PromQL-compatibility documentation page, so
there is nowhere else to record it.

Also stop cloning the series key columns when there is no offset, and stop
the `offset 0s` sqlness comment implying its parser error is evidence about
this fix -- the same message comes from a `u32` overflow in
`promql-parser`'s shared duration check (`offset 9999999999d`).

* fix(promql): record the subquery offset as the range fold offset

The subquery's `RangeManipulate` now shifts the payload timestamps by the
offset, so `predict_linear` over an offset subquery must recover the
evaluation time with that offset instead of 0.

* ci: retry failed nightly release on following weekdays (#9394)

Previously the nightly release was scheduled only on Mondays, so a
failed run left users without nightly builds for a whole week.

Now the schedule triggers every weekday at 00:00 UTC, but the release
only proceeds when the latest published nightly release is older than
NIGHTLY_RELEASE_MAX_AGE_DAYS (5) days. The check runs in
allocate-runners before any EC2 runner is allocated, and gates all
schedule-driven jobs (including the Slack notification, so a skipped
nightly is silent). Tag pushes and manual dispatches are unaffected.

* fix(promql): align timestamp() and label_join with Prometheus semantics

- timestamp() over a selector reports the selected sample's timestamp, without adding the offset.
- timestamp() over any other expression reports the evaluation time instead of the input value.
- label_join that overwrites an existing label rejects duplicate label sets at runtime.

* fix(promql): align label_replace and label_join edge cases with Prometheus

- label_replace leaves non-matching series unchanged instead of copying the source value into the destination label.
- label_replace may overwrite an existing label; duplicate label sets are rejected at runtime like label_join.
- label_join with no source labels removes the destination label, and an empty source label name is rejected.
- Empty label values produced by these functions are NULL, the same as an absent label.

* fix(promql): join absent labels as empty strings in label_join

concat_ws skips NULL arguments together with their separator, so a label that is absent (NULL) dropped its separator, e.g. label_join(label_join(vector(1), "a", "", "missing"), "b", "-", "a", "a") lost b="-". Read every source label as coalesce(label, '') like label_replace does.

* ci: make query regression non-blocking for scheduled nightly releases (#9434)

* ci: make query regression non-blocking for scheduled nightly releases

Scheduled nightly releases no longer gate publishing on the query
regression release test. The test still runs (validation policy stays
'all' for automatic releases) and uploads its report, but any result -
failure, timeout, cancellation, or skip - no longer blocks image
publishing or the GitHub release for schedule-triggered runs.

Since reusable-workflow caller jobs cannot use continue-on-error, the
gate is relaxed at the consumers instead: the if conditions of
release-images-to-dockerhub and publish-github-release now also pass
when github.event_name == 'schedule' regardless of the query-regression
result. All other gates (runner allocation, artifact builds,
prepare-release-validation) are unchanged.

Tag-push and manual-dispatch releases remain fully blocking unless a
skip policy is explicitly chosen via the release_validation input.

* fix(operator): bound FlowMirrorTask pending rows to prevent frontend OOM (#9421)

* fix(operator): bound FlowMirrorTask pending rows to prevent frontend OOM

When flownode is slow or unreachable, FlowMirrorTask::detach spawns
unbounded tasks that each pin a full insert batch for ~10s (gRPC
timeout). With continuous writes, in-flight memory grows unboundedly
(throughput x 10s x peers), causing frontend-write OOMKill and a
million-per-hour ERROR storm.

Add a MAX_MIRROR_PENDING_ROWS cap (1M rows) on Inserter: detach
fetch_adds the batch's row count before spawning; if the cap is
exceeded the reservation is rolled back, the batch is dropped, a
DIST_MIRROR_DROPPED_ROW_COUNT metric is bumped, and a warn is logged
instead of spawning. On normal completion the reservation is released
in both success and error paths.

This keeps core writes alive while degrading flow mirror writes to
best-effort, which is the intended trade-off: protect the primary
insert path at the cost of possible flow aggregation gaps.

P1: Compute pending_rows() from actual per-peer payloads in

share so reservations and releases balance.

P2: Replace load+set gauge publication with add/sub symmetry.
reserve_mirror_pending_rows does fetch_add + gauge.add, release does
fetch_update + gauge.sub, eliminating the stale-value race.

The duplicate-label-set rejection must not fire when a label rewrite keeps
every series distinct through another label. Normalizing mixed histogram
boundary representations (`10.0` -> `10`) while `instance` still differs is
the false positive reported in #9444. The check already accounts for it
since it became a per-timestamp row count instead of a planning-time
rejection, but no fixture covered the positive case. Add one, together
with the aggregation variant that produces a genuine duplicate and must
still fail.

* fix(promql): keep metric name for comparison operators (#9332)

* fix(promql): keep metric name for comparison operators

`collect_metric_names` dropped the response `__name__` for every binary
operator except `and` / `or` / `unless`, so comparisons such as
`node_load1 > 5` came back without the metric name. Grafana rendered them
as `{instance="..."}` and alert templates reading `$labels.__name__` got
nothing.

Follow Prometheus' `shouldDropMetricName` / `resultMetric`: arithmetic
operators drop the name, comparisons keep the left-hand name, except when
the comparison returns a bool or is a one-to-one `on(...)` match. A
`group_left` / `group_right` modifier does not reduce the labels, so the
name is kept there.

Both the HTTP PromQL API and the gRPC gateway share
`retrieve_metric_name_and_result_type`, so one fix covers both.

* perf(promql): reduce timestamp payload allocations and use narrow cursor scans (#9417)

* perf(promql): zero-copy timestamp payload for millisecond zero-offset ranges

RangeManipulate rebuilt the timestamp range payload per sample through
wide-precision i128 conversion even for millisecond input with zero
offset, where the input is already millisecond and nothing changes.
That turned a previously zero-copy path into a per-sample loop plus a
Vec allocation, regressing range-function queries.

Reuse the input timestamp array directly when the time index is already
millisecond and the offset is zero. Other units and non-zero offsets
keep the wide-precision conversion (required so ns/us data near the
native type limits stays correct under large offsets).

RangeManipulate::calculate_range and InstantManipulate::manipulate
compared every sample through i128 wide-precision arithmetic. For
realistic timestamps and offsets the shifted values stay far inside
i64, so the wide path was pure overhead.

Split both scans into an i64 fast path (checked arithmetic precomputed

overflow i64 falls back to the i128 scan, keeping window membership
semantics identical.

Restore the zero-copy fast path for millisecond timestamps with zero
offset, guarded by the input column's exact data type (Timestamp
(Millisecond, None)) rather than self.time_unit. The old time_unit guard
would accept a tz-carrying millisecond column and produce a dictionary
value type disagreeing with the output schema; the datatype guard is the
correct check.

Also fix the comment: arrow's try_unary is a fallible kernel that LLVM
cannot auto-vectorize; the win over the hand-written loop comes from
eliminating the per-sample Option/Vec and branches, not SIMD.

Add a regression test with a timezone-carrying millisecond index to
prove it falls back to the try_unary path.

* perf(promql): replace try_unary with unary + Cell overflow flag

Arrow's try_unary is a fallible kernel that LLVM cannot auto-vectorize.
Replace it with the infallible unary kernel: the closure is a plain
i64 -> i64 mapping that sets a Cell<bool> on overflow instead of
returning Err per sample. The flag is checked once after the loop.

This removes the per-lane Result construction and lets LLVM vectorize
the shift+truncate sequence. Bench (N=4096, 15s cadence):
- window4x15s: 42.12us -> 28.77us (-32%)

* build: keep build inputs checkout-relative for cross-worktree cache reuse

Two small changes so compilations are byte-identical across worktrees
of the same commit and can share a build cache (mbx, sccache):

- src/common/version/build.rs: derive the workspace root relative to
  CARGO_MANIFEST_DIR instead of the CARGO_WORKSPACE_DIR injected by
  .cargo/config.toml (an absolute path). The env var remains as an
  explicit override for the submodule case; the [env] injection in
  .cargo/config.toml is removed so the relative derivation is used by
  default.
- Replace three env!("CARGO_MANIFEST_DIR") uses in test/bench code
  (servers prom_decode bench + decode test, common-meta test_util)
  with a runtime std::env::var lookup, so the compiled artifact no
  longer embeds the checkout path.

No behavior change: same files are read, same version info emitted.

* ci: benchmark the object store WAL against S3 from an EC2 runner (#9536)

* ci: benchmark the object store WAL against S3 from an EC2 runner

Add a workflow_dispatch workflow that loads the o11ybench agent observability
dataset into a fresh GreptimeDB container per cell and compares three WAL
configurations that differ only in [wal]: Raft Engine with sync_write on the
instance store, and the object store WAL in durable and enqueued mode, with
the data files on S3 in the runner's region for all three. Rounds alternate
the configuration order. A summary reports rows per second, D/R and E/R as
the geometric mean over rounds, append acknowledgement p50 and p99, and the
object store WAL counters. A smoke mode runs the same chain on ubuntu-latest
against the MinIO fixture.

* ci: scrape WAL metrics on failed loads and keep logic out of the benchmark YAML

Scrape the object store WAL metrics before stopping a cell's server whether
the load succeeded or failed, so failed cells keep their stall, poison and
create failure counters. Build the summary from the plan so that cells which
never ran are listed and leave their ratios undefined. Move budget, region,
runtime image, manifest and credential scan logic from the workflow into the
helper scripts, and drive the cell lifecycle in the tests through fake docker
and curl binaries.

* ci: fail a benchmark cell whose metrics scrape fails and zero untouched WAL counters

A load that succeeds without its metrics scrape now fails the cell with exit
code 4 and records metrics_scraped in cell.json. The summary reports an
event counter that never registered as zero when the cell is an object store
WAL cell whose scrape succeeded and created objects, and as unknown otherwise.
Planned cells that never ran are read through the same path as recorded ones.

* ci: register the S3 benchmark workflow for dispatch from its branch

A workflow_dispatch workflow can only be dispatched once GitHub has
registered it, which happens on the default branch or when one of its
triggers fires. A push trigger limited to this branch registers it; validate
runs only for workflow_dispatch, so a push run skips every job.

* ci: delete the benchmark S3 prefix one object at a time

boto3 now sends a CRC checksum instead of Content-MD5 with DeleteObjects,
which the MinIO fixture of the smoke run rejects. DeleteObject needs neither
and the prefix of one run holds at most a few thousand objects.

* ci: default the S3 benchmark to c6id.2xlarge

c7id is not offered in the runner region ap-southeast-1, where DescribeInstanceTypes

* ci: fail an S3 benchmark run on EC2 without a local instance store

Without an instance store the Raft Engine WAL of the R cells silently stayed
on the root EBS volume, so the run measured a different baseline. Only a smoke
run may keep it on the root volume now.

Signed-off-by: jeremyhi <fengjiachun@gmail.com>

* ci: let the instance store check fail its workflow step

The step piped wal-disk into tee without pipefail, so a rejected host still

* fix: align fulltext bloom tokens with matches_term and use them for LIKE

The bloom fulltext index stored tokens that did not follow
matches_term's word boundaries (`_`, ASCII next to Han, Han substrings),
so pruning dropped rows matches_term accepts.

Tokens and query probes now share the character classes of
matches_term, Han runs are indexed as bigrams, and LIKE patterns use the
same probes. The bloom blob is written under a new key; blobs from older
versions are no longer probed. Tantivy no longer serves matches_term.

Case-insensitive bloom indexes also store the tokens of the whole

so matches_term(lower(col), ..) and lower(col) LIKE .. use the index.

* fix(query): accept narrowed nullability in MergeScan remote schema check (#9592)

On append-mode tables a region reports an exact row count. When it is
zero, DataFusion's AggregateStatistics replaces the region-side
__min_state/__max_state aggregate with a non-null struct literal, so the
remote stream advertises the state column as non-nullable. The MergeScan
schema check required equal nullability and failed the query.

Accept a remote field that is non-nullable where the expected field is
nullable, matching DataFusion's own physical-plan schema invariant.
Batches are already rebuilt with the expected schema. Widening is still
rejected, and nested field nullability is still compared exactly as part
of the data type.

RegionScanExec reported null_count = 0 and distinct_count = total_rows for

Keep the exact row count and an exact zero null count for non-nullable

discord9 28e415a103 feat(query): implement PromQL @ modifier on vector and matrix selectors (#9224)
* feat(query): implement PromQL @ modifier on vector and matrix selectors

The planner previously dropped the `at` field of selectors (`at: _`),
so `some_metric @ 300` silently returned step-following values instead
of the samples anchored at the fixed timestamp.

Anchoring follows Prometheus's `setOffsetForAtModifier` + `refetch`
semantics: resolve the anchor (`@ <ts>`, `@ start()`, `@ end()`), apply
`offset` to the anchor, rewrite the selector offset to
`eval_start - anchor`, scan only the anchored window, then report the
same window at every evaluation step via a grid-wide-replay
`InstantManipulate`. `@ start()` / `@ end()` resolve against the
statement's evaluation range (`stmt_start` / `stmt_end`), which subquery
planning does not rewrite.

Timestamps before the Unix epoch are accepted; unrepresentable ones are
rejected with `AtModifierTimestampOutOfRange` instead of wrapping.
Selectors without `@` are planned exactly as before.

* fix(promql): center predict_linear on the evaluation timestamp

predict_linear_impl used the window's last sample time as the evaluation
timestamp, and the UDF took only (ts_range, value_range, t) with no channel
for the current instant. After a range selector is folded for @ (or with an
offset) the same window is replayed at every step, so the prediction stayed
constant at the anchor's answer; even a plain window ended before the step
produced a stale value.

Give prom_predict_linear a 4th argument carrying the step's evaluation
instant (ms timestamp), derived in the planner from the row's time index
plus the offset the window was folded with (at_offset for @, offset_ms
otherwise, recorded on PromPlannerContext). The regression is centered on
that instant, matching Prometheus' use of enh.Ts. The mixed
float/native-histogram path forwards the same argument.

* refactor(query): tighten @ modifier planner and predict_linear

- range_fold_offset is always a concrete millisecond offset, not an
  Option; the single-step replay helper no longer wraps an infallible
  plan in Result.
- predict_linear's eval timestamp is always cast to Timestamp(ms) at the
  call site, so the UDF drops its dead Int64 branch and the extra
  func_name argument.
- Drop two redundant comparison cases from the at_modifier sqlness test
  and fix the lookback window comment to the half-open (0s, 300s].

* test(query): accept parse-time rejection of @ on Windows

`@ 1e16` is 10^19 milliseconds, beyond i64::MAX. A Unix SystemTime
holds it and the planner rejects the anchor it cannot represent, but a
Windows SystemTime tops out near 1.8e12 seconds, so the parser's
checked_add fails first and the same literal is rejected while parsing.
Accept either rejection path so the test passes on both platforms.

discord9 4ffd93d8dc fix(query): preserve global limits with DataFusion optimizer fixes (#9071)
* fix(query): preserve global fetch through physical-optimizer repartitioning

Aggregate soft-limit pushdown inserts a global CoalescePartitionsExec(fetch)
below an AggregateExec whose input is HashPartitioned/KeyPartitioned. The
DataFusion physical optimizer's EnforceDistribution/EnforceSorting passes then
dropped or rewrote that fetched coalesce, losing the global limit. Root-caused

* fix(query): keep count_values generated label in enclosing expressions

`count_values("v", m)` projects the generated label as a real output
column, but did not register it in `ctx.tag_columns`. Enclosing
expressions (abs/round/+1/topk/label_replace/vector join) rebuild their
projection from `ctx.tag_columns` and silently drop the label.

Register the generated label in `ctx.tag_columns` after the projection,
and give it the same qualifier as other tag columns so qualified
references resolve. PromQL overwrites an input label with the same name,
so drop any existing tag with that name first to avoid duplicate column
ambiguity.

* fix(flow): keep count_values generated label as sink table primary key

FindGroupByFinalName::f_up only renamed a group key when the projection
aliased the key column directly. count_values now projects its generated
label as a unary UDF over the sampled column
(prom_float_to_string(value) AS label) while the aggregate still groups
by the raw column, so the name match failed and the sink table lost the
label from its PRIMARY KEY, demoting it to a DOUBLE value column.

Allow a projection above the aggregate to rename a group key by deriving
its output from a single group-key column (unary scalar function or cast
over that column only). Multi-column expressions, case, aggregates,
windows, subqueries and literals are still rejected so a computed column
cannot be mistaken for the group key.

* fix(query): group count_values by the formatted sample value

The numeric count_values branch grouped by the raw sample column and only
formatted the value into the generated label in the post-aggregate
projection. Two distinct raw values that collapse to one label text
(e.g. BIGINT 9007199254740992 and 9007199254740993, both 9007199254740992
in Float64) were split into two groups, each emitting the same label set
at one timestamp, violating Prometheus' unique-label-set-per-timestamp
invariant.

Return the formatted value expression (prom_float_to_string, with a
CAST to Float64 for non-Float64 inputs) as previous_field_expressions so
the aggregate groups by the same expression that produces the label,
mirroring the existing mixed float/native-histogram precedent.

* fix(flow): don't replace group key with derived unary expr

FindGroupByFinalName treated any unary expression of a single group
column (scalar fn, Cast, TryCast) as a rename of that group key and
swapped it in as the sink primary key. A derived expression such as
lower(host) is many-to-one, so distinct groups (HOST_A vs host_a) would
collapse to the same primary key and be silently deduplicated.

Narrow the matching to direct name-matched aliases of the actual group
expression only, and drop the derived-unary path (is_unary_expr_of_column)
and the allow_derived flag. count_values already groups by the formatted
expression name, so it is unaffected.

Add a regression asserting host survives and host_lc does not replace it
under both optimizer settings.

The runner forced both environment and instance parallelism to 1 whenever

Only distributed uses the kv backend, and the two environments use
different Kafka topic prefixes, so they can run at the same time. Keep one

and Kafka topics. Runs with a runner-managed Kafka, an external server, a

dennis zhuang 88197f4019 fix(promql): derive vector matching result labels and reject ambiguous matchings (#9306)
* fix(promql): derive vector matching result labels and reject ambiguous matchings

A vector-vector binary operation projected one operand's whole tag set and
inner-joined without any cardinality check, so `on()`/`ignoring()` did not
reduce the result labels, `group_left`/`group_right` changed nothing, and a
non-unique match group produced a cross product that PromQL cannot represent.

Result labels now follow Prometheus `resultMetric`: `on(...)` keeps the
matching labels, `ignoring(...)` drops them, and a group modifier keeps the
many side's labels plus the `group_x(...)` labels taken from the one side.
A label the one side does not carry is deleted from the result. The reduced
label set no longer identifies the operand series, so `__tsid` is dropped
from the context on this path.

Cardinality is enforced with a `count(1) OVER (PARTITION BY match keys, ts)`
window and a scalar UDF that fails the query on a repeated group: on the one
side before the join, and on the result labels after it, matching where
Prometheus raises each of its three errors. Series are unique by their whole
tag set, so the window is only planted when the match keys drop a tag; plain
arithmetic and `on(<all tags>)` plan exactly as before.

Closes #9207, closes #9208, closes #9209.

* perf(promql): keep __tsid when the result labels are an operand's whole tag set

Deriving the result labels dropped `__tsid` from the context unconditionally,
so an enclosing operation fell back to joining on the tag columns even where
the column still identified the result series.

Keep it when every result label comes from one operand and covers that
operand's whole tag set: no other operand value reaches the labels, and the
matching gives each of its rows a single partner, so its `__tsid` is still one
per result series. That is the common `on(<all tags>)` and bare `group_left`
shape; a matching that actually drops a tag still clears it.

The column is re-qualified as the result's own, which is how the enclosing
expression and the context look it up.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* fix(promql): keep the match group count column unambiguous

The cardinality check aliased its row count to a fixed `__promql_match_group_count`.
An operand carrying a label of that name made the window output two fields with
the same name, and planning failed with "Schema contains qualified field name
collide_right.__promql_match_group_count and unqualified field name
__promql_match_group_count which would be ambiguous".

Pick a name the operand does not already have, the way the `or` operator
allocates its match key columns.

* test(promql): cover a match group spread over several regions

The cardinality check runs above the merge of the region scans, so it counts a
match group globally. Nothing pinned that: every table in these cases holds a
single region, and a check evaluated per region would pass them all.

Partition the operand on a column outside the match keys, which puts the two
series of one match group in different regions, and assert both the pre-join
and the post-join check still reject it. The case runs in the distributed
environment too, where the regions sit on different datanodes.

* fix(promql): group an outer aggregate on the labels the operand kept

`by`/`without` planning topped up a missing grouping column by walking down to
the table scan and re-projecting it. That is right for a column the scan pruned
for efficiency, but the labels a matching modifier deletes are also absent from
the operand's output, and they were restored the same way:

  sum without(host) (a / on(host) b)

`on(host)` leaves the operand with `host` alone, so the sum covers everything
and Prometheus answers `{} 10`. Instead `device` came back from the scan under
`a` and split the result into `{device="d1"} 5` and `{device="d2"} 5`. Same for
`sum by(device)` of that operand, which has no `device` to group on at all.

Take the grouping labels from the operand's own label set rather than from the
row keys of the scan beneath it. A label pruned from the plan is still in that
set and still gets restored; a label the operand dropped is not.

* refactor(promql): drop the unreachable aggregation tag top-up

`by`/`without` planning could restore a grouping column that the plan no longer
carried by rewriting the scan underneath it. Once the grouping labels come from
the operand's own label set, there is nothing left for it to restore: a scan
projects every label of `ctx.tag_columns` (`scan_tag_columns` only ever adds
matcher columns to that set), so a label in the set is always in the schema.

Stubbing the rewriter to a no-op passed the whole sqlness suite, in both the
standalone and the distributed environment.

* test(promql): drop cases that guarded the removed tag top-up

Three plain selector aggregates were there to show that restoring a pruned

engine scan prunes tag columns: it projects every label of the operand.

* docs(promql): note the duplicate a propagated matcher hides

A matcher copied onto the one-side operand removes groups without a partner
before the cardinality check sees them, so a duplicate in such a group is not
reported. Prometheus checks every group of the one side and fails the query.

no longer detects unused dependencies against current cargo internals —
unused deps have landed on main undetected (e.g. humantime in

- CI: install cargo-shear in the check-udeps job; drop the build cache
  and protoc steps (cargo-shear never compiles)
- Remove ~150 unused dependency declarations found by cargo-shear, move
  misplaced deps to the correct sections, drop orphaned
  [workspace.dependencies] entries (arrow-cast, rustc-hash)
- Add [package.metadata.cargo-shear] ignored entries with explanations
  for dependencies that are structurally required despite no textual
  reference: sqlparser (required by sqlparser_derive expansions in
  datatypes, common-query), common-error (required by common-macro's
  stack_trace_debug expansions in session, tests-fuzz), k8s-openapi
  (feature-pinning for the transitive kube dependency in tests-fuzz),
  tikv-jemalloc-sys (link-only, enables jemalloc profiling features in
  common-mem-prof), protobuf (required by build.rs-generated bindings in
  log-store)

* ci: create docs follow-up issue on PR merge instead of on label (#9237)

* ci: create docs follow-up issue on PR merge instead of on label

The docbot workflow previously created a docs-repo issue as soon as the
'docs-required' condition was detected (PR opened/edited with the docs
checkbox ticked), even if the PR was never merged.

Now the workflow also triggers on PR 'closed':
- opened/edited: only manage the docs-required/docs-not-required labels
- closed: create the docs issue only when the PR was actually merged and
  carries the docs-required label

This also lets maintainers control issue creation by manually adding or
removing the docs-required label before merging.

Signed-off-by: Ning Sun <sunning@greptime.com>

* fix: address review comments on docs issue creation timing

- Only touch docs labels when the docs checkbox state actually changed
  in an edit. Previously, editing any other part of the PR body while
  the checkbox stayed checked removed the docs-required label, silently
  dropping the docs follow-up now that issue creation happens at merge.
  Unchanged checkbox now leaves labels untouched, which also preserves
  manual label overrides.
- Do not trust the closed event's stale label snapshot at merge time:
  re-read the live PR via the API and create the docs issue if the
  docs-required label is present OR the checkbox is ticked in the
  current body.
- Make the workflow concurrency group action-aware so a merge run does
  not cancel an in-flight label update from an edit run.

Signed-off-by: Ning Sun <sunning@greptime.com>

* fix: make docs-required label the single source of truth at merge

The label-OR-checkbox merge condition could not distinguish an
intentional opt-out from an unfinished label update: removing
docs-required while the checkbox stayed checked still produced an
issue, and unchecking the box could still produce one if the merge
read the stale label before the edit run removed it.

At merge time, wait for any pending docbot runs on the PR head SHA to
finish their label updates (bounded to 5 minutes), then decide solely
by the live docs-required label. Adds actions: read permission for
listing workflow runs.

`preserves_filter` ended in `_ => true`, which was only sound because

alone would have silently pushed a matcher below a label rewrite. List the

test_repartition_metric ran four format/primary-key-encoding cases in a

Each case builds its own 3-datanode cluster and runs a full repartition
plus GC cycle, so on S3 the metric test took 165-178s against the 180s

Split each case into its own test. Cases were already independent, so
they now run in parallel and each stays far inside the timeout, and a
failure points at one encoding instead of four.

discord9 233e23b352 fix(promql): keep value-field grouping labels out of matching filter propagation (#9242)
* fix(promql): keep value-field grouping labels out of matching filter propagation

#9202 propagates matching-label matchers to the scanned selector using the
planned operands' tag columns. For an aggregated operand those are its
grouping labels, and agg_modifier_to_col resolves by(...) names against the
input schema only, so a value field named in by(...) is reported as a tag.
A value field varies between the samples of one series, so lowering a
matcher on it below sample selection (PromInstantManipulate) can drop the
newest sample, promote a stale one from the lookback window, and fabricate
a match the un-rewritten query does not produce.

Track the by(...) labels that name value fields of the aggregated operand's
input in PromPlannerContext::aggregation_field_labels, and refuse to
propagate matchers on them while still requiring a matcher to name a
grouping label to cross an aggregation.

* fix(query): insert MergeScan into nested scalar subqueries

DataFusion 55 keeps uncorrelated scalar subqueries as expression
subqueries (enable_physical_uncorrelated_scalar_subquery, default true)
instead of decorrelating them into joins, and executes them via the new
physical ScalarSubqueryExec. DistPlannerAnalyzer::try_push_down walked
the plan with a plain TreeNode transform that does not descend into
expression subqueries, so MergeScan was only inserted for depth-1
subqueries. A scalar subquery nested inside another scalar subquery kept
a bare frontend DistTable TableScan and failed at execution with
"Unsupported operation: get stream from a distributed table".

Use the subquery-aware transform so handle_subquery (PlanRewriter /
MergeScan insertion) runs for subquery plans at every nesting depth.

Fixes #9260.

dennis zhuang 007836ba7a fix(prometheus): honor label matchers in __name__ values query (#9134)
* fix(prometheus): honor label matchers in __name__ values query

`/api/v1/label/__name__/values?match[]={pod="abc"}` dropped every matcher
other than `__name__` and returned all metrics in the schema. No error,
just the wrong list. Grafana's metrics browser sends this request, so
picking a label value there did nothing.

Selectors that only constrain `__name__` keep answering from table
metadata. A selector constraining an ordinary label now goes to the data:
scan each metric engine physical table for distinct `__table_id` in the
time range, map the ids back to metric names, then apply the selector's
own `__name__` matchers.

Only metric engine tables are covered; other engines share no column space
to scan.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* refactor(prometheus): batch-resolve metric names by table id

Building a full table-id-to-name map meant walking every table in the
schema and holding all of them in memory, just to name the handful the
scan returned. Use `tables_by_ids` instead — one batch KV read over the
ids the scan actually produced.

The catalog walk stays, but only to find the physical tables to scan.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* fix(promql): read an absent label as the empty string

A matcher on a label the series does not carry only worked when the table
had no column for it at all. Where the column exists but is NULL on that
row -- the norm for logical metrics sharing a metric engine physical
table, which holds the union of their label columns -- three-valued logic
dropped the row, so `host!="host1"` and `host=""` missed every metric
without a host label.

Coalesce nullable string label columns to "" for matchers that accept the
empty string, rather than only for the OTLP temporality marker. Equality
matchers are untouched; they cannot match NULL either way.

This is the Prometheus compatibility fix #8970 deliberately kept out of
its own scope. The cost is visible in the regex sqlness plan: the
predicate becomes a CASE, so the scan loses its LastRow selector and
grows a FilterExec. Only negative and empty-accepting matchers pay it.

* fix(promql): don't panic on pre-epoch label value bounds

`rewrite_label_values_query` unwrapped `duration_since(UNIX_EPOCH)`, which
returns an error for an instant before the epoch. `start=1969-12-31T23:59:59Z`
parses as valid RFC3339, so the request panicked instead of answering.

Recover the sign from the error branch, and report a value beyond i64
milliseconds as an error rather than wrapping the cast.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* refactor(prometheus): drop applicable_matchers, share the distinct scan

With the planner reading an absent label as empty, the frontend no longer
needs to pre-filter matchers per physical table. Removing that exposed a
second problem: a physical table that never took a column from a logical
table exposes no `__table_id`, and projecting it failed the whole request.
Skip those tables; the only thing that can miss is a metric with no labels.

Also pulls out the plan-build-execute-collect sequence the two label value
scans had in common.

discord9anddiscord9 983738101a feat(flow): admit mergeable average states in incremental plans (#9235)
Incremental batching flows already merge sink state for scalar
aggregates and the HLL/UDDSketch/stddev state families. AVG now exposes
a mergeable Binary state (avg_state / avg_merge with
__avg_state_delta_merge), so admit those aggregates too instead of
forcing a full snapshot for flows whose only state column is an
average.

merge_op_for_aggregate_expr takes the aggregate input schema so the
avg_merge arm can require a Binary state argument; the state form is
the aggregate result persisted by the sink, so no extra coercion is

discord9 27090496d1 test(flow): stabilize FLUSH_FLOW assertions after async source-table mirrors (#9230)
* test(flow): wait for async source-table mirrors before FLUSH_FLOW

Streaming flows execute inline in the flownode insert handler since
#8976, and source-table inserts are mirrored from the frontend as
detached tasks. Tests that INSERT then ADMIN FLUSH_FLOW then SELECT
intermittently miss rows on slow CI runners because the flush no longer
implies the mirror reached the flownode (flow_no_aggr lost row 'l',
flow_advance_ttl lost row '23' after the post-restart reinsert).

Add SQLNESS SLEEP 3s between those mirror inserts and the flush, the
established pattern in the flow suite, so the assertions are stable.

* test(flow): also guard first-section flushes in flow_advance_ttl

Local reproduction without sleeps failed in a window the previous
commit did not cover: the first INSERT (20,20,22) of each section is
followed immediately by ADMIN FLUSH_FLOW, and the distributed run
observed an empty sink on that SELECT (~1 in 8 iterations). Add the
same SLEEP 3s guard before those two flushes.

dennis zhuang b1106a9c5a perf(promql): propagate matching-label filters between binary operands (#9202)
* perf(promql): propagate matching-label filters between binary operands

A one-to-one arithmetic binary expression inner-joins its operands on the
matching labels, so every row that survives the join already satisfies the
other operand's equality matchers on those labels. Copy those matchers to the
other operand so both scans drop non-joining series before execution instead of
feeding them to the join.

Both operands are planned before the rewrite: a selector matcher can also
constrain a value field, and only the planned contexts tell tags and fields
apart. A matcher is copied only when its name is a tag column on both sides, its
value is non-empty, and it is one of the matching labels. Operands are limited
to vector selectors, parentheses, and label-preserving range functions applied
directly to a matrix selector; `ignoring(...)`, group modifiers, fill values,
set and comparison operators, regex matchers and `or` matcher groups are left
alone.

Selector matchers are now deduplicated in place instead of through a `HashSet`,
so the generated scan filter keeps a stable order once a selector carries more
than one matcher.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* perf(promql): propagate ignoring, non-equality and aggregated matchers

Widens the matcher propagation added in the previous commit to the shapes it
was leaving on the table.

The join compares matching labels with plain column equality
(`normalized_match_key_expr` and its coalescing are confined to `or`), so any
predicate on a matching label is already enforced on both sides for every
surviving pair: it originates on one operand, and the join carries it to the
pairs it forms. Copying it to the other operand can only drop rows that had no
surviving partner. That argument does not depend on the matcher kind, so regular
expressions, negations and empty values now propagate too. `=~".*"` stays out:
it lowers to no filter at all, so copying it would only force a re-plan.

`ignoring(...)` is no longer rejected. A label is a join key exactly when it is a
tag on both sides and not named in `ignoring`, which is what
`binary_join_key_columns` computes and what the caller can now answer from the
two planned contexts.

Operands may now be aggregations that partition by their grouping labels, which
is the shape most real queries use. `agg_modifier_to_col` rewrites
`ctx.tag_columns` to the grouping labels, so a label found in an aggregated
operand's tags is a group key, and filtering the aggregate's input by it drops
exactly the corresponding output groups. `topk`, `bottomk` and `limitk` are
excluded because they select across a group and carry input labels through --
`prom_topk_bottomk_to_plan` leaves `ctx.tag_columns` alone, so the tag check
cannot catch them. `count_values` is excluded because it adds an output label
that does not exist in its input.

The rollup whitelist now covers every label-preserving range function the
planner implements, and finds the matrix argument by position so multi-argument
rollups such as `quantile_over_time` and `predict_linear` qualify.
`absent_over_time` stays out: it synthesizes a series from the matchers when its
input has none.

Re-running the sqlness case against an unmodified planner produces a
byte-identical `.result` for all 27 queries.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* test(promql): pin that excluded matching labels stay on their own operand

`ignoring(device)` and `on(host)` both leave `device` out of the join keys, so a
`device` matcher must not reach the other operand. Neither case was covered end
to end: a regression there silently drops the left operand's `eth1` series
instead of returning them, which the two added queries now catch.

Also corrects the comment at the rewrite site, which still described re-planning
as touching a leaf selector. Aggregated operands are re-planned as a whole; what
holds is that the rewrite only ever adds matchers to a selector, so the enclosing
operand's table reference, time index and field columns are unchanged.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* refactor(promql): log why matching-filter propagation was skipped

Splits the guard chain into `try_propagate`, whose `Err` names the reason the
rewrite does not apply, and logs it once in `propagate`. Debugging a query that
did not get the filter no longer means stepping through the guards.

The reasons also replace the comments that used to explain the same conditions,
and the remaining comments lose the parts that restated the code or repeated
each other.

Two of them were wrong rather than verbose. Saying `topk`'s input "must not be
filtered" reads as a claim about PromQL: `topk(1, m{host="x"})` is perfectly
legal, and what matters is that filtering before `topk` changes the candidate
set it ranks. Saying the subset-matching case "keeps its many-to-many result"
read as an endorsement of behaviour Prometheus rejects outright; it now records
that the query is a cross product here and points at #9209.

The propagation cannot change whether such a check would fire: series in one
match group agree on every matching label, so a matcher over one of those labels
keeps all of them or drops all of them.

Signed-off-by: Dennis Zhuang <killme2008@gmail.com>

* fix(promql): keep copied matchers out of the operand's selector metadata

Re-planning an operand with a copied matcher also rebuilt its
`PromPlannerContext::selector_matcher`, and that context is what an enclosing
expression reads. `create_absent_plan` turns the equality matchers found there
into the labels `absent()` reports, so

    absent(counter_metric{host="missing"} / on(host, device) gauge_metric)

gained a `host="missing"` label that `main` does not produce. The inner
expression was empty either way; only the reported label set changed.

The copied matcher belongs to the scan, not to the operand's identity, so both
re-planned contexts now keep the matchers their operand was written with.
`selector_matcher` has one other reader, `create_table_scan_plan`, which
consumes it while the operand is being planned and is unaffected.

* fix(function): return canonical AVG1 state for empty window frames

DataFusion's plain-aggregate window executor bypasses the accumulator
and calls default_value() directly when a window frame contains no
rows. create_udaf's SimpleAggregateUDF derives default_value from the
return type, which yields SQL NULL for Binary output instead of the
canonical AVG1 empty state, so empty frames and frames over only NULL
inputs became observable differently (IS NULL, direct state saves,
state comparisons).

Register avg_state/avg_merge through a small AggregateUDFImpl (AvgUdaf)
that keeps the existing accumulator and declares the canonical AVG1
empty state as default_value, restoring the documented contract. Add a
unit test asserting default_value equals the empty accumulator's
evaluate() and an sqlness case covering the empty-frame window.

* perf(promql): rescan windows that barely overlap

Reusing candidates loses to a plain scan when consecutive windows overlap
little: the deque bookkeeping then costs more than the rescan it replaces.
A local Criterion run on 4096 samples at width 240 / step 240 measured
10.79 -> 22.14 us for min and 12.83 -> 19.85 us for max.

Pick the evaluator once per batch from the first two windows. RangeManipulate
emits one window length and one step per batch, so that sample decides for all
of them, and both evaluators return identical bits, so a wrong pick costs time
only. Batches that do not qualify fold each window on its own.

Move the incremental state into SlidingExtrema so tests can drive it directly:
the exhaustive four-sample differential test cannot reach it through a UDF
call, because such a batch never qualifies for reuse.

Signed-off-by: Dennis Zhuang <xzhuang@greptime.com>

* fix(promql): select the extrema evaluator from batch averages

Reading the window shape off the first two windows misreads the batch.
RangeManipulate starts a series at max(query start, first aligned sample),
so a series that begins inside the query range gets a first window covering
roughly one step, and a window covering no sample at all is emitted as
(0, 0). Either one closed the gate for the whole batch, including the
one-hour window at a 15s step that candidate reuse was written for.

Compare the batch averages instead: at least 32 samples per window, and a
step advancing at most a quarter of that. Uniform batches select exactly as
before, so the thresholds keep the meaning they were measured with.

The 32-sample rule had also moved most of the benchmark and query-regression
shapes onto the rescan, including the case built to measure reset and
rebuild. Widen those windows to 40 samples, add a step at the selection
boundary, and add an end-to-end case with 40-sample windows advancing 5.

Signed-off-by: Dennis Zhuang <xzhuang@greptime.com>

* fix(promql): ignore empty windows when measuring batch advance

The advance was read from the first and last window offsets, but a window
covering no sample is emitted as (0, 0). A query whose last evaluation lands
exactly one window past the last sample ends on such a window, and its zero
offset made a batch of disjoint windows look like one that never moved, which
selected the evaluator built for overlap. Results stayed correct; the cost was
deque bookkeeping on the shape the scan fallback exists for.

Take the offset span over the windows that cover a sample. Empty windows stay
in the window count, where they only make both conditions stricter.
