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. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * 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. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * 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 duration_count. Agent calls compute it from the child spans they already aggregate. The projection contract goes from 16 to 18 columns; every branch projects both. Explicit column queries are unaffected, `SELECT *` and ordinal-based readers see the new shape. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * test(semantic-graph): drop the duplicated source-gate case The whitelist gate on `source=opentelemetry` is already covered by `otel_implicit_declarations_are_gated` and by the wrong-source case in `table_semantics`; here it only paid for another table create, insert and full graph derivation. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * style(semantic-graph): trim the comments back to what the code cannot say Several comments restated the code, repeated a rationale already stated at the type or in the RFC, or explained a test in more words than the test body.

dennis zhuang	09c0b23a23	feat: manage semantic table options via ALTER TABLE SET/UNSET (#8880) ... * fix(meta): actually acquire logical table locks in alter-logical-tables procedure The procedure listed its logical table locks from table_info_values, which is only filled during Prepare, while procedure lock keys are fixed at submission — so the logical locks were never acquired. Today every writer of a logical table's info is serialized by the physical table lock, which hides the problem; a metadata-only alter procedure targeting a single logical table would race it. Resolve the logical table ids at submission, persist them in the procedure state (serde(default): state dumped by older versions keeps the previous behavior), lock physical + logical tables, and re-check the resolved ids against the locked set at Prepare so a table dropped and recreated after submission cannot be mutated without a lock. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * feat: manage semantic table options via ALTER TABLE SET/UNSET CREATE TABLE accepts greptime.semantic.* options, but ALTER TABLE SET routed every option through SetRegionOption, whose closed match rejects them — tables auto-created by ingestion could never receive semantic declarations after the fact. Semantic options are pure metadata markers no region consumes, so they now take a metadata-only alter, following the repartition-hint precedent: - New AlterKind::SetAnnotations/UnsetAnnotations carrying an AnnotationFamily (currently only Semantic), so future marker-style option families reuse the same machinery. The converter classifies a SET/UNSET batch by key prefix and rejects batches that mix annotation keys with regular options. - The procedure reuses the MetadataOnly flow: no region dispatch, table-info update plus cache invalidation only. - Validation lives in the table-meta mutation layer, so it runs at frontend verification and again in the procedure's prepare step under the table lock: SET is strict (known key, value domain, entity columns exist and render as strings); UNSET is lenient inside the namespace so stale keys can be cleaned up. ModifyColumnTypes re-checks columns referenced by entity declarations at the same layer, closing a verify-then-execute race. - Logical metric tables are supported: an annotation alter submits a regular alter-table task locking only the logical table, and the DDL manager's physical-route guard admits it. - create_table_info re-checks semantic value domains for gRPC-built expressions that bypass the SQL parser. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * refactor(table): centralize annotation option classification and validation Address review feedback on the AnnotationFamily abstraction: with only one variant that every consumer immediately destructured, the generality was fake. Make it real and exhaustive instead: - AnnotationFamily gains RepartitionHint: repartition.column.hint is the same kind of marker option (pure metadata, no region consumes it) and previously had a hand-rolled special case in the converter, the metadata-only classifier, and a dedicated AlterKind pair — all deleted, one classification API remains. Per-family logical-table eligibility (allows_logical_tables) replaces the hard-coded Semantic check in the DDL manager guard. - One validation core in the table crate (check_annotation) serves both DDL entry points. CREATE and ALTER previously duplicated the rules; each keeps its existing error variants, status codes and messages via thin adapters over a typed error (ALTER missing column stays 4002 TableColumnNotFound, CREATE stays InvalidArguments). - The batch classifier returns Result instead of swallowing the mixed-batch error: a mixed SET on a logical table now reports the actual problem instead of UnexpectedLogicalRouteTable, and the flow classifiers propagate instead of guessing. The converter also moves its owned payloads instead of cloning them. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * test(meta): cover logical-table annotation alter routing The route-guard branch admitting metadata-only annotation alters on logical tables was only exercised end to end by sqlness. Pin it at the DDL manager level: a semantic SET on a logical table succeeds, updates only the logical table's metadata and dispatches nothing to datanodes; a mixed batch reports its own error instead of the route guard's; the repartition hint stays rejected on logical routes. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * fix(table): keep entity guard on ADD COLUMN and report missing columns first Review follow-ups: the old verify_alter loop scanned the post-alter schema, so it also caught DROP COLUMN followed by re-adding the declared column with a non-string type — the mutation-layer move only kept the MODIFY path. Guard add_columns the same way (this also covers ingestion auto-alter). And run the MODIFY drift check after the existence lookup, so altering a dropped-but-still-declared column reports ColumnNotExists (4002) like every other MODIFY on a missing column. Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * style(grpc-expr): drop a test comment restating the classifier doc Signed-off-by: Dennis Zhuang <killme2008@gmail.com> * refactor(table): rename annotation validation helpers per review check_annotation* validated and normalized; align the names with the validate_and_normalize_* convention nearby, and spell out AnnotationContext (Cx is not used in this repo).

dennis zhuang	d6c37778ae	feat: table semantic layer information_schema view (Phase 3) (#8240) ... * feat: table semantic layer information_schema view (Phase 3) Add `information_schema.table_semantics`, a queryable view over the table semantic layer. One row per table that carries at least one `greptime.semantic.*` option: the signal-agnostic keys (signal_type/source/pipeline/metadata_quality) are promoted to columns and the remaining signal-specific keys are folded into a `semantic_options` JSON string. Tables with no semantic key are excluded. Stacked on Phase 2.
