* refactor(servers): simplify Flight coalescing with append-then-check accumulator

Remove the lookahead/pending machinery and coalesce with an
append-then-check soft budget. Extract the group state into a private
BatchAccumulator so the ordinary stream loop reads as a short control
flow: append each ready batch, flush when a budget is reached.

Budgets are flush thresholds, not memory limits, so a group may exceed
a budget by the final appended batch. First-batch direct send and
singleton passthrough for a batch that starts a group already at a
budget are unchanged.

* refactor(servers): split Flight stream into dispatcher and per-path units

FlightRecordBatchStream::flight_data_stream held two large side-by-side
branches (the verbose/ANALYZE metrics path and the plain/coalescing
path) inline, making the function hard to read. Split it into a small
dispatcher that keeps only the shared prologue (schema send, metrics
init) and the shared EOF final-metrics tail, and move each branch into a
self-contained unit:

- verbose path -> Self::verbose_metrics_stream
- plain/coalescing path -> private CoalescingBatcher (owns the
  BatchAccumulator, sent_first_batch, and schema)

Each path returns whether it reached normal EOF; the dispatcher skips
the shared final-metrics tail on any early error/failed-send exit,
preserving the exact pre-split behavior (an early return previously
exited the whole function and bypassed the tail). No behavior, metrics
ordering, or coalescing semantics change.

Add a regression test that drives flight_data_stream directly and
asserts the verbose error path does not invoke the final-metrics tail
(producer-side metrics() call count), since the public message stream
hides the tail after an error.

* perf(servers): avoid copying over-budget batches and release merged inputs

Three review-driven improvements to Flight batch coalescing:

- After a successful merge, reuse the drained vector in place
  (clear + push the merged batch) so the source batches are dropped
  before the send loop instead of staying alive across a backpressured
  send.

- A batch that is itself at/over a budget is forwarded as a singleton
  even when encountered inside an accumulation group: the accumulated
  group is flushed and sent first, then the over-budget batch. This
  avoids copying a large batch into an aggregate just to merge the small
  batches ahead of it. Under-budget append-then-check is unchanged
  (600+600 still merges).

- Strengthen two tests: the first-batch test now drives the producer
  directly and asserts the upstream poll count is exactly one at the
  first-batch send; the dictionary test now decodes the merged
  dictionary keys to assert the logical values, so a key-remapping
  regression is caught.

* perf(servers): raise Flight coalesce row budget to 4096

mito2 commonly emits ~2000-row batches (~32-94KiB), so a 1024-row budget
marked every such batch oversized and the coalescer forwarded them
unbatched. Measured on a local distributed cluster (2M-row table):

- full selector: 1000 -> 337 batches, p50 latency 4133 -> 3316 ms (-20%)
- range scan:    501 -> 206 batches, 1466 -> 1162 ms (-21%)
- small/olap queries (single-series, top-k, group-by): unchanged

Larger budgets (8192 rows, or 1-4MiB bytes) coalesce more batches but do
not improve latency further and slightly regress it, so 4096 rows is the
sweet spot; MAX_BYTES stays at 256KiB and MAX_BATCHES at 16.

dennis zhuang 7cbd20a053 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.

* 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.

dennis zhuang 577de012b2 perf(servers): group Prometheus response rows by label runs (#9092)
* perf(servers): group Prometheus response rows by label runs

Query output tends to be clustered by series, but a matrix response read
the same label values out of the tag columns once per row, and allocated
a key vector per row to look the series up.

Use `arrow::compute::partition` to find the runs of rows that share their
labels and build the series key once per run. The key buffer is hoisted
out of the row loop and handed to the map only when the series is new,
through the raw entry API so the key is hashed once either way.

Partitioning does not pay off when rows are not clustered, so a few
adjacent row pairs are probed first to pick between the run path and the
row-by-row path. Both paths produce the same series.

Drop the per-row "same labels as the previous row" check from #8815. Runs
cover the clustered case it was written for, and it now costs more than
it saves: 10% on a result with one row per series, 1-3% on clustered ones.

* refactor(servers): find label runs with cmp::distinct

`arrow::compute::partition` computes the same ranges on the same kernel,
but its contract takes lexicographically sorted columns, and query output
is not sorted: range queries run without the plan's output sort since
#9090, `sort`/`topk` order by value, and the tag column order in the
schema does not have to match any sort key. An implementation that
exploited the precondition would merge `a, b, a` into one run and
attribute one series' samples to another, without failing.

`cmp::distinct` is element-wise, so it holds for any row order, and its
null handling is the one a series key needs: a null label and an empty
one are distinct, two nulls are not. Building the ranges from the
boundary bitmask also folds away the `tag_columns.is_empty()` case, since
no columns means no boundaries means a single run.

Same kernel, so the benchmark does not move: -1.4% to +1.4% across shapes
with no consistent sign, against +-3% run-to-run drift.

Lei, HUANG 21aed0371f feat(pprof): switch CPU profiler to framehop unwinder (#9125)
* feat(pprof): switch CPU profiler to framehop unwinder

Replace the default libgcc-based unwinder in pprof-rs with the
framehop unwinder, which is designed to be async-signal-safe:

- framehop performs no heap allocation during unwinding
  (MustNotAllocateDuringUnwind)
- It handles prologue/epilogue interruption correctly
- It falls back to frame-pointer unwinding when CFI is unavailable
- It does not depend on libgcc's unwind implementation, which is
  documented as not signal-safe (see tikv/pprof-rs#36)

Bump pprof from 0.14 to 0.15 in all three consumers (common-pprof,
cmd, servers) to unify on a single version. pprof 0.15 also replaces
parking_lot with spin-rs to avoid a potential profiler deadlock (#268).

This addresses the libgcc_s.so.1 #GP crash observed in production
when CPU profiling is active, by eliminating the libgcc unwinder
from the signal handler path entirely.

* fix(pprof): gate framehop-unwinder to supported targets

framehop-unwinder is only available on x86_64/aarch64 Linux/macOS.
Enabling it unconditionally for all Unix targets breaks the build on
riscv64 and other platforms: pprof disables its backtrace-rs fallback
when framehop-unwinder is set, but the framehop module is not compiled
on unsupported targets, leaving no TraceImpl implementation.

Split the pprof dependency: the base target.'cfg(unix)' block carries
the common features (flamegraph, prost-codec, protobuf), and a separate
target block adds framehop-unwinder only on supported targets.
Cargo unions features from both blocks on matching targets, so x86_64
and aarch64 Linux/macOS get the full feature set while other Unix
targets fall back to the default backtrace-rs implementation.

* fix: bump jemalloc crates to 0.7 and patch tikv-jemalloc-sys with tcache init fix

Upgrade tikv-jemallocator / tikv-jemalloc-ctl / tikv-jemalloc-sys from
0.6 to 0.7, which embeds jemalloc 5.3.1 (includes a056c20d 'Handle
tcache init failures gracefully').

On top of that, patch tikv-jemalloc-sys to the GreptimeTeam fork that
adds the remaining upstream fix 54f22c83 'Initialize TSD tcache before
enabling it' (GreptimeTeam/jemalloc#1, GreptimeTeam/jemallocator#1).
Without the ordering fix, a reentrant allocation during TSD bootstrap
(e.g. heap-profiling prof_tdata init / sampled backtrace when prof:true
is active) can observe an enabled-but-uninitialized tcache, corrupting
per-thread tcache metadata and crashing the process in arena_stats_merge,
calloc, or the libgcc unwinder.

The patch is pinned by rev and should be removed once tikv/jemallocator
ships a jemalloc snapshot that includes 54f22c83.

dennis zhuang 02278d301b feat: derive k8s.node from OTLP resource attributes (#9002)
The k8s.pod runs_on k8s.node rule can only fire from kube_pod_info: it is
the only table declaring both endpoints, and co-declared edges require
both on the same row. A deployment sending only OTLP has no
kube-state-metrics tables, so its node layer is invisible and that rule
has no source at all, even though the resource attributes carry
k8s.node.name.

Declare k8s.node in otlp_trace_entities and in the synthesized resource
descriptor, and project k8s.node.name in the descriptor writer so the
column the declaration needs exists. Identity is the name rather than
k8s.node.uid: kube-state-metrics carries no node UID, so the name is the
only identity both sources can agree on.

dennis zhuang 109257505e feat: report what the graph derives and fix two duplicate-node bugs (#8936)
* feat(semantic-graph): let the generic container yield to k8s.container

A container inside a Kubernetes pod reaches the graph twice: as the
k8s.container entity kube-state-metrics describes, identified by
[pod uid, container name], and as the generic container the OTel resource
attributes describe, identified by container.id. One physical container,
two nodes.

Kubernetes is the primary scenario, so k8s.container keeps its identity
and the generic type stands down where it applies. Conventions gain a
row-level condition for that: `suppressed_by` withdraws a declaration on
rows where any of the named columns has a value. The test has to be per
row, not per table — one descriptor table holds both pod rows and
bare-runtime rows.

Every branch that turns a declaration into rows now shares one guard
(`declaration_predicate`), so the condition cannot apply to entities but
not to the edges they carry.

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

* feat(semantic-graph): report derived entity declarations in table_semantics

information_schema.table_semantics only read table options, so the
declarations the built-in conventions derive — for trace tables, for
whitelisted Prometheus and OTel descriptor metrics — were invisible.
"Why is my table not in the graph?" was answerable only from debug logs,
which is not a self-service path.

A new `entity_declarations` column reports the entities a table actually
contributes: each one's identity, whether it came from an option or from
the conventions, and any row-level condition attached to it. An expected
entity missing from the list is the answer — the table name is not
whitelisted, the source stamp is wrong, an id column is absent.

The row filter widens to match: a table that declares nothing by option
but derives entities by convention now appears, since it is in the graph
and the view has to say so. The provider reaches the derivation through a
new metadata-only trait method, keeping catalog below operator.

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

* fix(semantic-graph): never yield a container to an entity nothing derives

The generic container withdrew on any row carrying a pod UID, on the
assumption that k8s.container would cover it. Nothing guaranteed that:
k8s.container came only from kube-state-metrics, so an OTLP-only
deployment — or one whose KSM data had expired or fell outside the query
window — lost the container node and its edges entirely instead of
gaining a more specific one.

The rule now names the superseding type rather than a trigger column, and
withdraws only where that type's full identity is on the row. Both OTel
sources declare k8s.container themselves, under the identity
kube-state-metrics gives it ([pod uid, container name]), so the two
sources name one node; `k8s.container.name` joins the descriptor's
projected attributes to carry it.

Resolution runs once every declaration for the table is known, so a
superseding type that ends up undeclared — its columns are gone, or an
explicit declaration of it was skipped — leaves the guard empty and the
generic container standing. A container can change type; it cannot
disappear.

* refactor(semantic-graph): build the declaration JSON by serializing a type

The column was assembled entry by entry into a serde_json::Map, cloning
every value and allocating a String per key. A Serialize struct that
consumes the declaration moves the same data instead, and the field order
now reads type, origin, identity, then description.

The scan path around it was doing the same kind of avoidable work:
declarations were derived before the predicate could discard the table,
the supersession pass cloned every declaration's identity to look up one,
and the option parse claimed the time index for tables that turn out to
declare nothing.

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

* feat(semantic-graph): keep the structured identity for single-column ids

`entity_id_attrs` was NULL whenever the identity came from one column, so a
consumer holding `host` = `a3f2...` had no way to tell which column produced
it, and no way back to the source table. Most identities are single-column —
host, k8s.pod, k8s.node, service — so the common case was the opaque one.

Build the JSON object unconditionally. Entity equality still reads `entity_id`
alone, so this changes no merging: it records which attributes the id was
assembled from, beside an id that deliberately omits them.

Also corrects the `entity_id` column doc, which still described the `k=v,k=v`
rendering replaced in #8904 by values joined in declared order.

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

* fix(semantic-graph): keep what a container carried when it yields

Yielding to k8s.container cost the row two things it had as a generic
container. The runtime container id, which kube_pod_container_info keeps
descriptive precisely because it is the handle back to runtime logs and
metrics, went missing entirely: neither an id nor an attribute of any
node. And the edge vocabulary knew only the generic type, so a row with
the more complete labels ended up with fewer connections than one
without — the container layer no longer reached its host.

Both OTel sources now keep the runtime id and name descriptive on
k8s.container, and the vocabulary gains the two edges that mirror the
generic type's. Nothing checks a supersession against the edge
vocabulary, so that requirement is written down where the rule is.

Also: the conventions-failure path now reports the explicit half as its
comment always claimed, entity_declarations reports scope columns, and
identifies() is private again now that only declaration_predicate calls
it. The two RFCs catch up with entity_id_attrs being unconditional, the
view listing convention-derived tables, and supersession existing.

* feat(semantic-graph): report unmatched clients and the longest request

`real_wins` pins a `calls` edge's RED metrics to the observed span pairs:
when a window's edge key holds any pair, the unmatched client spans are
suppressed so one (window, edge) yields one row. That leaves no way to
tell a callee that stopped responding from traffic that stopped arriving —
both show up as a lower request_count.

Add two columns to `semantic_relationships`:

- `unmatched_count` — client spans with no server span, counted outside
  `real_wins` on the same row, so the suppressed population stays visible
  without splitting the edge into two rows. NULL for agent calls, whose
  inner join leaves nothing unmatched, and for declared edges.
- `duration_max` — the longest single request. It goes through
  `real_wins`: a pair is timed by the server span while an unmatched
  client is timed by its own (network wait included), so mixing them would
  make the max describe a different population than duration_sum and

dennis zhuang 6d86e6ff06 feat: synthesize OTLP resource descriptor for the semantic entity graph (#8904)
* fix(servers): compose OTLP metrics job from service.namespace/service.name

The OTel Prometheus compatibility spec defines job as
"<service.namespace>/<service.name>" when the namespace is present.
The OTLP metrics path only used the bare service.name, so the job tag
diverged from target_info produced by Prometheus-side exporters for the
same resource. Compose the namespace form, and keep not fabricating a
job when service.name is absent.

Behavior change: resources carrying service.namespace now get
"namespace/name" as their job tag value.

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

* feat(otlp): synthesize otel_resource_info at OTLP metrics ingestion

Ordinary OTLP metrics scatter filtered resource attributes as tags over
every logical metric table, so metrics-only services contribute nothing
to the semantic entity graph. Each request now also projects its
distinct resources into one info-metric-shaped mito table,
otel_resource_info: a fixed allowlist of identity-relevant attributes
under their raw OTel keys (independent of the label translation
strategy and the promote/ignore headers) plus derived job/instance
compatibility columns, value 1.0, and the newest data-point timestamp.

The descriptor is written after the main insert is committed; a failure
there (conflicting pre-existing table, auto-create disabled) degrades
to an OTLP partial_success warning with rejected_data_points = 0
instead of failing the request and triggering client retries of
already-accepted data. A request writing a metric named
otel_resource_info suppresses synthesis. Legacy mode is unchanged.

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

* feat(operator): otel info-metric conventions with host/container entities

Whitelist the ingestion-synthesized otel_resource_info descriptor via a
new otel_info_metrics conventions map, gated on source=opentelemetry
(the existing gate hardcoded source=prometheus). Its declarations use
explicit descriptive lists instead of descriptive_rest so identifying
attributes of other entities do not leak into service.instance.

Conventions tightened per the Astronomy Shop findings: host identity is
host.id with host.name descriptive only (host.name is not stable across
SDKs and resource detectors), a generic container entity (new entity
type) is declared only when container.id is present, and trace-v1
tables now synthesize host/container from their flattened resource
attributes too. New co-declared edges: service.instance runs_on
container, container runs_on host.

* test(otlp): cover the resource descriptor in integration tests

Covers the descriptor's raw-key columns and info-metric options through

names being independent of the translation strategy, the allowlist
excluding unlisted resource attributes, auto-create after a drop, the
metric-name collision suppressing synthesis, and the partial-success
warning (rejected_data_points = 0) when a pre-existing incompatible
table fails the descriptor write while metric data is accepted.

* fix(frontend): degrade descriptor permission denial to a warning

A table-level permission policy denying otel_resource_info would have
failed the whole OTLP metrics request because the descriptor's
permission check ran before the main insert. The descriptor is derived
enrichment: check its permission in the degrade path so a denial skips
the write and surfaces as the partial-success warning, like any other
descriptor write failure.

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

* fix(otlp): guard descriptor writes with semantic ownership markers

A pre-existing schema-compatible table named otel_resource_info would
silently receive descriptor rows while its missing semantic stamps kept
it out of the entity graph. The descriptor write now requires the
auto-created table's ownership markers (mito engine + signal_type +
source + metric.type=info + metadata_quality=declared) and otherwise
degrades to the partial-success warning; the entity-graph gate for the
otel whitelist likewise requires metric.type=info, so a user table
stamped with only signal/source no longer picks up implicit
declarations.

Also fold the descriptor write cost into the response and surface the
degrade warning through the otel-arrow BatchStatus status_message.
Integration tests pin the full marker set on auto-create and that an
existing owned descriptor keeps accepting writes without degrading —
a missing marker would otherwise silently stop every descriptor write
after the first request.

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

* perf(otlp): build descriptor rows without the per-resource BTreeMap

Projecting a resource allocated a BTreeMap and then collected it into the
row key, and every attribute was matched against the allowlist by linear
scan. Collect the tags into a Vec and sort once, and match the allowlist
instead of scanning it. Measured on the conversion path: descriptor work
drops 16-18%, from 10.6% to 8.9% of conversion CPU on the worst shape
(1000 resources with 4 data points each), where the cost tracks resource
count rather than data-point count.

Also trims the comments and tests added with the descriptor to what
carries information.

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

* test(otlp): pin the descriptor permission-denial degrade path

A policy denying the descriptor table must not fail the metrics request,
which the fix in 2401b3dd9c does but nothing covered. Verified as a

the main write makes this test fail.

* test(otlp): keep legacy mode covered after trimming the unit tests

Trimming the descriptor tests dropped the only assertion that legacy
mode skips the job/instance remap and the promote filter. Both alter
the columns of tables already in use, so fold the check into the legacy
conversion test rather than leaving it uncovered.

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

* fix(semantic-graph): stop encoding column names into composite entity ids

A composite entity id rendered the identifying columns as sorted
`col=value` pairs, so the same identity split into one entity per
signal: a trace table names its columns service_name and
resource_attributes.service.instance.id where a metric table names them
job and instance. One service instance became two nodes with two
parallel edge sets, breaking the walk from a trace to that instance's
metrics.

Render an id as its values in declared order instead, escaping the
separator so components stay distinguishable, which is what single-column
ids already did by keeping only the value. entity_id_attrs still carries
the structured form.

Values alone are not enough for a namespaced service: the metric side
folds service.namespace into job while traces keep the bare name. Add
qualified_by to the conventions so the trace declarations compose the
namespace the same way, per the OTel rule that job is
<service.namespace>/<service.name> or the bare name when the namespace
is empty. A table without the namespace column keeps the unqualified
identity rather than losing the declaration.

Conventions validation now rejects one entity type declared with a
different number of id columns by two sources, which would silently
produce ids that can never match.

* feat(otlp): gate the resource descriptor, and fix what review found

Synthesizing greptime_otel_resource_info creates and writes a table the
user never sent, so it is now off unless
otlp.experimental_enable_resource_info says otherwise. With it off the
request costs exactly what it did before the descriptor existed: nothing
is projected, no table is created, no write and no permission check
happen. Tests run with it on. StandaloneOptions carried no otlp field,
so the whole [otlp] section was silently dropped in standalone mode; map
it through, or the new option (and trace_ingest_chunk_size before it)
would do nothing there.

Renamed from otel_resource_info: the greptime_ prefix marks the table as
engine-managed and makes a collision with a user metric unlikely, which
is what the pre-existing-table ownership check and its per-request
catalog lookup were defending against. Both are gone.

A request may carry data for several graph windows, but the descriptor
folded every data-point time into one row at the newest of them, leaving
the earlier windows with metric rows and no entities. Key the rows by
window as well, and take the times from the data points the encoder
actually writes: it drops exponential histograms, and a resource
carrying nothing else was being described as an entity with no
measurements.

Projecting a resource cloned its attributes once per data point. Nest
the windows under the attributes instead, so they are moved once per
resource, and walk the data-point times through a visitor rather than
collecting a Vec per metric.

Also documents what the two maps key and hold, and lifts the projected
attribute names to constants beside KEY_SERVICE_NAME.

* fix(otlp): skip the descriptor's work entirely when it is disabled

The collision scan over the request's output tables ran even with the
feature off. Short-circuit on the option instead, and update the config

had attached itself to the trait impl and described a check that no

and the descriptor takes its timestamps through exponential_histogram_value
so per-point rejections drop out too.

* perf(servers): speed up Prometheus JSON response building with ryu and per-series entry reuse

PrometheusJsonResponse::record_batches_to_data spends ~47% of its CPU
in f64::to_string() per sample and ~32% in IndexMap::entry() per row
(60s profile of concurrent query_range workloads, ~800k series).

- Replace f64::to_string() with ryu::Buffer::format_finite for finite
  values (shortest round-trip, 3-5x faster); NaN/+Inf/-Inf keep the
  previous std formatting so wire output is unchanged.
- Remember the previous row's label vector and entry index; query output
  is clustered by series, so consecutive rows reuse the same IndexMap
  entry via get_index_mut instead of rebuilding and hashing the label
  vector (worst case adds one Vec comparison per series transition).

Also adds a query-regression case (prom_json_response) that measures the
real Prometheus HTTP range API path (/v1/prometheus/api/v1/query_range),
which is the only frontend path that builds the Prometheus JSON response
(TQL ANALYZE formats the SQL JSON shape instead), plus a prom_http query
kind in the regression runner.

Perf (aligned base d90cca4b75, 256 series x 481 points):
- prom_range_2h (JSON response path): 29.31ms -> 21.46ms (-26.8%)

Ning Sun 174577164a feat: otlp duration_nano and trace_flag signed integer coercion (#8816)
* feat(servers): add signed→unsigned int coercion to OTLP ingest path

Phase 0 of transitioning built-in data models from unsigned to signed
integers (#8793): add lossless Int64→UInt64 and Int32→UInt32 coercion
arms so existing UInt64/UInt32 columns (e.g. trace `duration_nano`, log
`trace_flags`) keep accepting new signed ingest without an ALTER TABLE.

The OTLP ingest path already reconciles every incoming column against the
existing table schema and treats it as authoritative. With these arms,
`choose_trace_reconcile_decision` returns `UseExisting(UInt64/Uint32)`
for an existing unsigned column receiving signed data: the table keeps
its type byte-for-byte and the request value is coerced. No persisted
format is mutated; existing data stays readable as-is. This is the safety
net that makes the actual schema flip (Phase 1) safe.

Only the signed→unsigned direction is supported — the reverse would be
lossy for values above the signed range and is intentionally rejected.

Tests cover both new arms plus an end-to-end log test proving an existing
UInt64 column coerces an incoming Int64 value while keeping its type.

  check. Pin the schema with unit and integration tests.
- Reject spans whose end precedes their start (or whose duration does
  not fit i64) on the v1 path instead of wrapping: new Int64 tables and
  existing UInt64 tables now fail identically, rather than storing
  negative durations that break the Jaeger query API.
- Extract is_supported_signed_to_unsigned_coercion so the trace and log
  ingest paths share one supported-pair predicate and cannot drift.

  Durations above i64::MAX saturate rather than wrap.
