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 and fixed in the DataFusion fork (GreptimeTeam/datafusion PR #35); this repo pins to that fix commit and adds regression coverage. - pin datafusion to GreptimeTeam/datafusion 48510c7f5 (fetch preservation fix) - global_limit.rs: adapt to new DF API (input_distribution_requirements, child_distribution, replace_children+Recompute); accept HashPartitioned and KeyPartitioned as partitioning to restore; add regression unit tests - sqlness: extend standalone common ssts and refresh distributed ssts_limit result for the preserved fetch plan Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * refactor: drop dead HashPartitioned compat arms and test wrapper - remove HashPartitioned compatibility matches (pinned DF only emits KeyPartitioned); drop their #[expect(deprecated)] attributes - remove single-use agg_with_limit helper whose seed limit is always overwritten by the soft-limit transform - restore Cargo.lock dependency edges unrelated to the DataFusion pin bump (cargo update --precise had downgraded 26 unrelated packages) Addresses oracle ablation review.

fix(query): keep count_values generated label in enclosing expressions (#9223)
* 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(query): drop needless borrow in count_values test helper
Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com>
* 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.

test(sqlness): run environments concurrently and drop redundant restarts and sleeps (#9333)
* test(sqlness): run environments concurrently with external backends The runner forced both environment and instance parallelism to 1 whenever etcd/PG/MySQL or an external Kafka was set up, so the standalone and distributed environments ran one after the other. 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 instance per environment, since instances would share the metadata table and Kafka topics. Runs with a runner-managed Kafka, an external server, a test filter, or `-j 1` stay fully serial. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * test(sqlness): drop redundant restarts and sleeps - flow_rebuild: drop the R2 block, which repeats R1 from the same state, and the restart in R5, whose result R1 already asserts. - flow_advance_ttl, flow_view, ttl_instant: drop sleeps that no assertion depends on. - flow_basic, flow_null, flow_call_df_func: drop the bytes_log section (covered by flow_insert), a duplicate state_size query, an unchecked insert, and flushes that run with no new data. - alter_table_options, skip_wal: share restarts between independent tables. - session_skip_wal, copy_skip_wal: check every case after a single restart. Tables copied or inserted with skip_wal = true first get a WAL row that is truncated, so the check that truncated WAL entries are not replayed stays. - region_statistics: wait once for the statistics of all three tables. - build_index_table: fold its index_size checks into build_index_table_restart, which runs the same fixture and waits. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * test(sqlness): restore session_skip_wal and copy_skip_wal Checking every case after a single restart dropped two state transitions the original cases cover: recovering a region whose memtable only held skipped rows, and writing to the recovered region before restarting again. Restore the original cases.

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. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * 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. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * 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. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * 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. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * 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. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * test(promql): drop cases that guarded the removed tag top-up Three plain selector aggregates were there to show that restoring a pruned grouping column still worked. With the restore gone they only repeat what the aggregate cases already cover. Also fix a comment that still said the metric engine scan prunes tag columns: it projects every label of the operand. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * 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.

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.

* 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.

* 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.

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 needed. Other input types keep being rejected. Also cover avg_state, avg_merge and duplicate AVG projections in the incremental plan analysis tests, extend the mixed state-family rewrite test with an average column, and extend the standalone partitioned state-merge SQLness case with avg_state/avg_merge compared against a direct avg over the source.

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. Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * 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.

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.

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.

fix(mysql): strip leading comments before the federated statement filter (#9156)
* fix(mysql): strip leading comments before the federated statement filter JDBC clients prefix every statement with a comment. DataGrip sends `/* ApplicationName=DataGrip <version> */` in front of each one, and every pattern in the federated filter is anchored with `^`, so the prefix makes all of them miss. Two failures follow. `SET TRANSACTION READ WRITE` reaches the SQL parser and is rejected. Worse, the DBeaver-specific entries such as `^(/\* ApplicationName=(.*)SELECT @@(.*))` do match DataGrip's prefix, so `SELECT @@GLOBAL.event_scheduler` and `SHOW VARIABLES LIKE ...` are absorbed into a zero-column output, which the MySQL writer sends as an OK packet. The JDBC driver reports that the statement returned no cursor. Strip leading whitespace and comments before matching, and drop the ApplicationName-specific entries the stripping makes redundant. The three that had no unprefixed counterpart (`SHOW PLUGINS`, `SHOW ENGINES`, `SHOW @@...`) keep their behaviour as plain patterns. Also covers gaps found while probing the same path: - `BEGIN` is absorbed like `START TRANSACTION`/`COMMIT`/`ROLLBACK`. - `SHOW [GLOBAL|SESSION|LOCAL] VARIABLES|STATUS` parses; the scope is ignored because GreptimeDB keeps no global/session split. - `USER()`, `CURRENT_USER()`, `SYSTEM_USER()` and `SCHEMA()` are registered. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * fix(mysql): keep executable comments, reject multi-statement absorption Review follow-up on the comment stripping, plus the remaining MySQL compatibility gaps from #9155. `/*!...*/` is an executable comment: mysqldump emits its initialization as `/*!40101 SET NAMES ... */`, and the patterns match those verbatim. Stripping it left an empty statement, so nothing matched and the original SQL reached the parser, which rejects `SetNames` and `MultipleAssignments`. Leave executable comments in place. Absorbing a request also has to stop at a statement boundary, because every pattern ends in `(.*)`. `BEGIN; INSERT INTO t VALUES (1)` used to fail on the unsupported `BEGIN`; once `BEGIN` became absorbable the whole request would report success and write nothing. A request is now scanned for a second statement and handed to the query engine if it has one. The scan skips plain comments and string literals so a `;` inside either is not a boundary, and treats a `/*!...*/` that is not the request itself as a statement, since it carries SQL. `check()` now dispatches on the leading statement keyword, so INSERT, UPDATE, CREATE and ordinary SELECTs run no regex at all — this replaces the narrower hand-rolled INSERT shortcut. The statement scan runs only for a request the patterns already matched, which is always a short one. New compatibility surface: - `SELECT CURRENT_USER|SESSION_USER|SYSTEM_USER|USER` without parentheses, and `SELECT @var`, are answered here rather than in the parser. Both are anchored to the whole statement, so `SELECT user FROM t` still reads the column. - `information_schema.plugins`, `user_privileges` and `processlist` are registered as empty tables, like the other MySQL-shape tables around them. Sessions are reported through `information_schema.process_list` and `SHOW PROCESSLIST`; `processlist` carries the column shape only.

fix(promql): skip NULL samples and fix counter extrapolation order (#9118)
* fix(promql): treat NULL field values as absent samples in range functions Range functions read the value column through `Float64Array::values()`, which returns the raw buffer and ignores the null bitmap. A NULL field value means the series has no sample at that timestamp, so the padding under a null slot (0.0 in practice) was counted as a real sample. `rate`, `increase`, `delta`, `changes`, `resets`, `idelta`, `irate`, `quantile_over_time` and `avg_over_time` now work on samples instead of slots. `stddev_over_time` and `stdvar_over_time` used to panic on a NULL slot, and tokio swallowed the panic so the query returned success with that series missing. Null handling is gated on `null_count() == 0` over the whole backing array, checked once per batch, so tables without NULLs keep the existing code path. `deriv` and `predict_linear` already had this guard through `linear_regression_slices` and are untouched. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * fix(promql): keep other fields when one has no sample in the window Review follow-up. Two things surfaced once range functions started returning NULL for a window without samples. The filter after a function call required every field column to be non-NULL, so on a multi-field table one field with no samples in a window would drop the other fields' results with it. It now keeps a row when any field has a sample, which is the shape a selector already emits. On a single field column the two predicates are identical. `quantile_over_time` returned NaN rather than NULL for a window without samples, so the row survived that filter. Prometheus returns an empty vector there, so the emptiness check now sits in the range UDF; the shared quantile kernel still yields NaN for an empty slice, matching upstream's `quantile()` helper that `quantile_aggr` depends on. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * docs(promql): correct two comments on the null handling The planner one did not say why `preserve_any_value` is hardcoded at that call site, which is the question a reader arrives with. The `quantile_over_time` one described the empty-window behaviour while sitting on the `has_nulls` line, and that behaviour had moved into `window_quantile`. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * fix(promql): clamp extrapolation before snapping a counter to zero Prometheus clamps `durationToStart` to half an average interval once the first sample is past the extrapolation threshold, and only then lets the counter zero-snap shorten it further, so the snap can never lengthen the leading extrapolation. Running the snap first let it rescue a duration the clamp should have cut, and `rate` and `increase` over-extrapolated to the left. For samples 1@0s and 2@1s in a 4s window at 1s, upstream gives 0.375 and this returned 0.5. `extrapolation_matches_prometheus_on_seeded_windows` carries a line-by-line port of upstream `extrapolatedRate` as an oracle and diffs it against the UDF over seeded windows, so the order stays pinned. `factor` also picked up upstream's guard against a zero sampled interval, which previously divided by zero. Two sqlness results move, both verified against the upstream algorithm. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * test(promql): fold range_presence_null into null_samples #9104 landed its own NULL-sample case whose data is the same series this one already used: one host with interior NULLs, one host with nothing but NULLs. Keeping both means two files asserting the same semantics on the same rows. The merged case keeps every query from both, so the presence functions still cover the trailing-NULL window, the count of two, the empty left-open window at t=7, and the all-NULL windows.

fix(mito2): prevent JSON2 SWCS data loss from misaligned Parquet statistics due to projection (#9129)
* fix(mito2): look up row group stats by parquet leaf index for nested columns On flat-format tables a logical column can expand to multiple parquet leaf columns (e.g. a JSON2 struct stores the remainder and one leaf per promoted path). ParquetFlat used the logical column index in the SST schema directly as the leaf index when reading row group statistics, so min/max/null stats of every column after a nested column were read from wrong leaves. When the misplaced leaf held order-compatible statistics (e.g. a small Int64 JSON path vs. the timestamp window predicate), min-max pruning dropped whole row groups by mistake. SWCS compaction reads inputs with a time window predicate, so it silently lost all rows of such files; plain queries with time-range predicates were affected as well. Map each column to its first parquet leaf column and report NoStats for columns with multiple leaves, which makes pruning conservative for them. Add a unit test and a sqlness regression case that reproduces the data loss on the unfixed binary.

fix(promql): correct counter reset accumulation in rate windows (#9089)
* fix(promql): correct counter reset accumulation in rate windows `prom_rate` and `prom_increase` reused the previous window's counter-reset correction when the next window slid forward by exactly one sample, adding the entering reset and subtracting the leaving one. Running a sum through addition and subtraction does not restore the earlier terms in f64: a large reset absorbs the smaller ones that must survive it, and an expired infinity leaves a NaN that no later window can clear. `prom_delta` shares the code but is not a counter function, so it never took that path. Index the reset positions of the value array once instead, and reduce each window over the resets it contains, in sample order. The result is bit-identical to scanning the window directly, so windows keep the direct reduction when they request fewer sample pairs than the input has. Also sweep the query step in the rate benchmarks: the cost of the reset correction depends on how much the windows overlap, which no existing case varied. Signed-off-by: Dennis Zhuang <xzhuang@greptime.com> * test(promql): cover counter reset precision over adjacent rate windows The unit tests build the range windows directly, so they do not show that a plain PromQL range query produces the window layout that lost the correction. This case does: with a query step equal to the sample interval, `increase` over the second window returns 1.333 before the fix and 2.667 after it. Signed-off-by: Dennis Zhuang <xzhuang@greptime.com> * perf(promql): advance the counter reset bounds instead of searching Locating a window's resets with two binary searches costs more than the reduction it replaces once a series resets often enough for the searches to get deep: on a 20k-sample counter resetting every 37 samples, stepping the windows by one sample was 2.7x slower than the previous code, against 1.2x for a counter that never resets. Windows normally advance, so walk the bounds forward from the previous window and only search when they move back. The cost then no longer depends on the reset density. Signed-off-by: Dennis Zhuang <xzhuang@greptime.com> * perf(promql): cut the per-window cost of the counter reset index Two costs the index added showed up on a one-sample query step, where the removed fast path used to answer each window with two comparisons. Cache the two reset positions that bound the active slice. A window that only advanced and reached neither of them covers the same resets as the previous one, so the common case is four integer comparisons and no lookup at all. Stop summing the requested sample pairs once they exceed one pass over the values. The sum only decides which side of that comparison the input falls on, and a query with a short lookback and a long step settles it after a few windows instead of after every key. Together these take the one-sample step from 25-32% slower than the previous code down to 6-11%, measured as before / after / before to bound drift. No other step value regresses, and a ten-sample step stays about 88% faster. Signed-off-by: Dennis Zhuang <xzhuang@greptime.com> * fix(promql): accumulate counter resets into the running result `prom_rate` and `prom_increase` summed a window's counter-reset corrections on their own and added that sum to `last - first`. Prometheus folds each reset into the running result instead, and so did this code before #7880. The two are not interchangeable in f64: over samples `[1e16, 1, 0, 1]` the isolated sum rounds `1e16 + 1.0` back to `1e16`, which then cancels against the first sample and reports no increase at all, where folding the resets in one at a time keeps the 1.0. Restore the original order. The reset index accumulates into the result the same way, so it still matches a direct scan of the window bit for bit, but a window's contribution can no longer be cached as a standalone value and is re-added from its own difference each time. The bounds are still cached, so a window that did not cross a reset skips the lookup, and one that holds no resets returns without touching the index at all.

feat(mito2): introduce TWCS active window compaction (#9011)
* feat(mito2): support independent TWCS trigger_file_num for active and inactive windows Split the single TWCS trigger_file_num into per-window-state thresholds: the active window keeps the existing trigger (default 4, legacy compaction.twcs.trigger_file_num stays a compatible alias), while inactive windows use a new trigger (default 2). Inactive windows additionally fall back from balanced L0-only/L1-only candidates to a progress-making unbalanced mixed candidate so historical windows can converge; the active window retains the row/byte balance guards. Signed-off-by: Lei, HUANG <ratuthomm@gmail.com> * fix(mito2): bound inactive TWCS window convergence by rewrite budget Inactive windows that cannot compact within one level previously either stayed stuck (a threshold-qualified but unbalanced level returned no candidate without trying any fallback) or fell back to a mixed merge with no balance checks at all, which could rewrite a huge compacted file to absorb tiny fresh files. Inactive windows now converge progressively: threshold-qualified balanced picks, sub-threshold balanced single-level picks, a mixed merge whose total rewrite must fit in the output file budget, and finally an L0-only merge without balance checks. Windows that qualify for none of these are left uncompacted, bounding write amplification. Signed-off-by: Lei, HUANG <ratuthomm@gmail.com> * test(mito2): cover TWCS window trigger options in alter_table_options sqlness case Exercise SET/UNSET of compaction.twcs.active_window.trigger_file_num and compaction.twcs.inactive_window.trigger_file_num end to end, including that setting the canonical active key removes the legacy compaction.twcs.trigger_file_num alias from the table options. Signed-off-by: Lei, HUANG <ratuthomm@gmail.com> * fix(mito2): derive TWCS active window from the max-sequence file The active window was determined by the max event-time window among level-0 files. Between an L0 compaction removing its inputs and the next flush landing, level 0 is empty, so the active window transiently became None and every window fell back to the inactive rules - triggering full-window convergence merges during ongoing ingestion whose outputs are then superseded by new data. Flush and compaction outputs both inherit the max input sequence, so the file with the highest sequence across all levels always tracks the most recent write. Use its window as the active window, falling back to the previous L0-based rule when no file carries a sequence (legacy files). The new helper deliberately computes window keys with the assign_to_windows convention (truncate to seconds, then align up), because the result is compared against window keys produced there; the older ceil-based helper is kept unchanged for the legacy fallback path.

fix: re-scan stream-backed tables in recursive CTEs (#9039)
* fix: re-scan stream-backed tables in recursive CTEs A recursive CTE re-executes its recursive term on every iteration, but DfTableProviderAdapter hands StreamScanAdapter a single-use stream built at planning time. The second iteration failed with "Stream already exhausted" for every table served through DataSource::get_stream — information_schema, pg_catalog, the computed entity-graph tables and numbers. Keep that stream for the first execution and open a new one over the same scan request for later executions.

refactor(json2): concretize JSON2 schemas at merge scan boundaries (#9016)
* refactor(json2): concretize JSON2 schemas at merge scan boundaries Infer concrete JSON2 output types from remote plans and expose them on MergeScanLogicalPlan before physical planning. Recompute affected local schemas and remove the JSON2-specific rewrite from MergeScanExec. Add SQLness coverage for whole JSON2 columns in windows and joins.
