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.

* 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.

* 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
the HTTP path, the namespace/name job composition end-to-end, column
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.

* 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.

* 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.

* 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
regression guard by mutation: moving the permission check back before
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.

* 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
snapshot the new [otlp] section changed.

Also drops the doc comment orphaned by the deleted ownership check: it
had attached itself to the trait impl and described a check that no
longer exists.

* refactor(semantic-graph): drop the expect and name the service identity

The CASE is built through Case directly rather than the fallible
when().otherwise() builder, so the non-test path no longer carries an
expect (architecture-invariants $4).

service_identity returned two same-typed Options that both call sites
destructured positionally; a named struct makes a swap fail to compile.

Also records that id-column order is part of the identity, where the
option docs and the conventions authors will read it.

* fix(semantic-graph): cast duration_nano before the trace-table union

Trace tables written before the signed-integer ingest change hold

so a deployment holding both shapes could not build the plan. The
cross-table test now spans both.

* fix(otlp): decide exponential histogram acceptance in one place

The resource descriptor mirrored only the experimental gate, so with both
experimental flags on a resource whose only metric is a delta exponential
histogram was described as an entity with no measurements. The encoder's
whole-metric rules move into exponential_histogram_gate, which both call,
and the descriptor takes its timestamps through exponential_histogram_value
so per-point rejections drop out too.

Lei, HUANG 2182dccd9b fix: cap default runtime sizes to a minimum of 2 threads (#8908)
* fix: cap default runtime sizes to a minimum of 2 threads

RuntimeOptions derived its default sizes directly from num_cpus. On
single-core machines every runtime (global, compact, query, ingest)
ended up with one worker thread, which can easily deadlock async code
(e.g. block_on combined with spawn).

Clamp all CPU-derived runtime sizes to at least 2 threads.

* fix: init logging before runtimes so runtime options are logged

The global runtimes were initialized before the global logging
subscriber, so the "Creating runtime ..." info logs that carry the
runtime sizes were silently dropped. Initialize logging first in all
node start paths; common-telemetry has no dependency on
common-runtime, so the reorder is safe.

jeremyhi b30d17f89c docs: align wal.sync_period documented default with actual fallback (5s) (#8753)
The example TOMLs and generated config.md documented the default of
wal.sync_period as "10s", but since #5677 moved the WAL sync task to a
background RepeatedTask, an unset sync_period falls back to 5s in
RaftEngineLogStore. The two paths therefore had different fsync
periods: deployments based on the example configs used 10s while bare
configs used 5s.

Align the documentation with the actual code behavior (5s) instead of
changing the code fallback to 10s, so that no existing deployment
silently gets a larger data-loss window on host power loss.

- config/datanode.example.toml, config/standalone.example.toml: 10s -> 5s
- config/config.md: regenerated via make config-docs
- src/cmd/tests/load_config_test.rs: update assertions accordingly

dennis zhuang a585b83bfc fix: count Postgres SCRAM auth failures and correct auth config docs (#8538)
* fix: count Postgres SCRAM auth failures in the auth failure metric

The SCRAM SASL paths returned `Failed` without touching
`METRIC_AUTH_FAILURE`, so once SCRAM is enabled wrong-password and
unknown-user attempts disappeared from `greptime_servers_auth_failure_count`.

Funnel every SCRAM rejection through `record_scram_failure`, which records
one failure with a uniform `UserPasswordMismatch` label so the counter stays
useful without revealing whether the user exists.

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

* docs: correct per-protocol auth notes in config examples

The user_provider note no longer matched the implementation: pbkdf2_sha256
is excluded from Postgres SCRAM (so its iteration count is never exposed in a
SCRAM handshake), and the warning that hash-only verifiers cannot use MySQL's
native password handshake had been dropped.

State the actual per-protocol fallbacks and incompatibilities, scope the
iteration/salt enumeration caveat to pg_scram_sha256, and regenerate
config.md.

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

* fix: avoid double-counting Postgres SCRAM authorization failures

authorize() already increments METRIC_AUTH_FAILURE with its own status
code, so routing the authorization-rejection path through
record_scram_failure counted it twice, mislabeling the second increment
as UserPasswordMismatch. Return early to bypass the recorder.

* fix: harden Postgres SCRAM auth

- Verify the client-final nonce matches the server-issued nonce, per RFC 5802

- Replace the per-connection PBKDF2 over a random password for unknown users
  with a deterministic mock verifier keyed by the username and a process-wide
  secret. This avoids a CPU-exhaustion DoS on unknown usernames and removes a
  username-enumeration oracle: the SCRAM server-first salt and iteration count
  are now stable per username and indistinguishable from a real user, with no
  PBKDF2 cost and random keys that never accept a proof.

* fix: precompute stable SCRAM verifier for plaintext users

Plaintext-backed credentials derived a Postgres SCRAM verifier on the fly
on every connection, using a fresh random salt and running PBKDF2 each
time. That made a known plaintext user distinguishable from stored-hash
and unknown (mock) users through both the unstable server-first salt and
the per-connection timing, enabling username enumeration.

Precompute the SCRAM verifier once at load time (stable salt, default
iteration count) and reuse it, matching the mock verifier handed to
unknown users. Document that non-default iteration counts remain
observable in the SCRAM handshake and weaken enumeration resistance.

Lei, HUANG a3461caf9d feat: expose region read load metrics (#8316)
* feat: expose region read load through Prometheus metrics and heartbeat

Introduce region-level query load tracking (CPU time and scanned bytes)
collected by `RegionScanExec`, exposed via Prometheus metrics and optionally
reported through heartbeat region stats.

- **Region metrics** (`src/mito2/src/metrics.rs`, `src/store-api/src/metrics.rs`): Add
  `greptime_mito_region_query_cpu_time`, `greptime_mito_region_query_scanned_bytes`,
  and `greptime_mito_region_written_bytes_since_open` gauge metrics.
- **MitoRegion** (`src/mito2/src/region.rs`, `src/mito2/src/region/opener.rs`,
  `src/mito2/src/region_write_ctx.rs`): Replace `AtomicU64` `written_bytes` with
  `IntGauge`; add `query_cpu_time`/`query_scanned_bytes` fields with lifecycle
  management (init, reset, remove-on-drop).
- **RegionStatistic** (`src/store-api/src/region_engine.rs`,
  `src/store-api/src/storage/requests.rs`): Add `query_cpu_time` and
  `query_scanned_bytes` fields.
- **Metric-engine** (`src/metric-engine/src/utils.rs`): Aggregate query load from
  metadata and data regions.
- **Heartbeat** (`src/datanode/src/heartbeat.rs`,
  `src/common/meta/src/datanode.rs`): Relay region query load via heartbeat
  `RegionStat`; add test.
- **Query engine** (`src/query/src/options.rs`,
  `src/query/src/query_engine/state.rs`, `src/query/src/datafusion.rs`,
  `src/query/src/dist_plan/merge_scan.rs`,
  `src/query/src/dist_plan/analyzer.rs`,
  `src/query/src/dummy_catalog.rs`): Add `enable_region_query_load_report` config;
  wire `RegionScanExec` to accumulate CPU time and scanned bytes.
- **Table scan** (`src/table/src/table/scan.rs`,
  `src/table/src/table/metrics.rs`): Wire table scan metrics.
- **Config** (`config/standalone.example.toml`, `config/datanode.example.toml`,
  `config/frontend.example.toml`, `config/config.md`): Add example config and
  documentation for `enable_region_query_load_report`.
- **Tests** (`src/mito2/src/engine/basic_test.rs`,
  `src/mito2/src/engine/close_test.rs`,
  `src/cmd/tests/load_config_test.rs`,
  `src/flow/src/adapter.rs`): Add unit tests for region query load reporting

* feat: add password verifier formats

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

* fix: harden password verifier parsing and auth config errors

- Reject pbkdf2_sha256 verifiers whose hash is not 32 bytes and bound the
  salt length, preventing short-hash verifiers from matching on a prefix.
- Verify pbkdf2_sha256 with a stack-allocated buffer.
- Report only the length, not the bytes, when a mysql native password
  verifier has an illegal length.
- Map empty frontend_auth credentials to an invalid-config error instead
  of an internal error.

Internal flownode-to-frontend communication no longer authenticates
(see #8244), so the plain-text credential export path is dead code.
Drop get_one_user_pwd, its now-orphan as_plain_text helper, and the
related tests.

Yingwen 7840aa1bb4 refactor(mito2)!: remove PartitionTreeMemtable (#8080)
* feat: switch partition tree to bulk

Signed-off-by: evenyag <realevenyag@gmail.com>

* chore: keep partition tree memtable for migration test

Restore PartitionTreeMemtable construction when memtable.type=partition_tree
is explicit, and move the sparse-encoding bulk override into the default
(no explicit memtable.type) arm so phase 2's memtable.type=bulk wins on
reopen. Rewrite test_reopen_time_series_sparse_memtable_with_bulk to use a
metric-engine-shaped schema and sparse-encoded rows with WriteHint::Sparse,
so the test actually exercises a PartitionTreeMemtable in phase 1 and
verifies WAL replay into the new BulkMemtable on reopen without flushing.

Signed-off-by: evenyag <realevenyag@gmail.com>

* chore: drop partition tree memtable from runtime

Re-apply the unconditional sparse-encoding override in
`MemtableBuilderProvider::builder_for_options` and route the
`MemtableOptions::PartitionTree` arm to `BulkMemtable` with a deprecation
warning. After this change, `PartitionTreeMemtableBuilder` is no longer
reachable from the engine runtime; benchmarks still reference the type.

Remove `test_reopen_time_series_sparse_memtable_with_bulk` and the
`put_sparse_rows` helper added in the previous commit — that test only
existed to validate the PartitionTree -> Bulk reopen migration and is
unnecessary now that the override is in place.

* refactor(mito2): move timestamp_array_to_i64_slice into read module

Relocate the timestamp_array_to_i64_slice helper from
memtable/partition_tree/data.rs to the read module so that the read
path no longer depends on the partition_tree internals. All call sites
(both inside and outside the partition_tree module) now import from
crate::read.

Signed-off-by: evenyag <realevenyag@gmail.com>

* refactor(mito2): use TimeSeriesMemtableBuilder in time_partition tests

The time_partition tests use the memtable builder purely as a generic
backend for the TimePartitions write/scan paths; nothing in them is
specific to the partition-tree memtable. Switch the seven affected
tests to TimeSeriesMemtableBuilder so the tests no longer depend on
PartitionTreeMemtableBuilder.

Signed-off-by: evenyag <realevenyag@gmail.com>

* chore(mito2): delete PartitionTreeMemtable implementation

The runtime already falls back to BulkMemtable for the PartitionTree
variant. Drop the now-unreachable implementation, its metrics, the
partition_tree benchmarks, the metric-engine Unsupported fallback in
bulk_insert.rs, and the test helpers that only existed for the deleted
module.

MemtableOptions::PartitionTree, its parsing, the runtime fallback, the
store-api MEMTABLE_PARTITION_TREE_* constants, and the SQL fixtures
remain so existing region options keep round-tripping.

* refactor(mito-codec): drop skip_partition_column parameter

PartitionTreeMemtable was the only caller passing
skip_partition_column=true; every other caller passes false. Now that
the partition_tree module is gone, the parameter is uniformly false
and the guard branch is dead. Drop the parameter from the trait method
and both impls, remove the guard and the is_partition_column helper,
and update the four remaining call sites in mito2 plus the bench.

the SST format to flat in addition to clearing the memtable type.
