This enables storing telemetry data from AI coding\nassistants (Claude Code, Codex, Gemini CLI, etc.) directly into\nIoTDB\u0027s table model for local analytics.\n\nKey design decisions:\n- Reuses the existing REST service (Jetty + Jersey) on port 18080\n rather than introducing a new server or gRPC dependency\n- Database name is derived dynamically from each request\u0027s\n service.name resource attribute (e.g. claude-code -\u003e claude_code,\n codex -\u003e codex), so different tools land in separate databases\n- OTLP attributes are flattened into typed TAG/ATTRIBUTE/FIELD\n columns instead of being stored as opaque JSON blobs, enabling\n efficient time-series queries without JSON parsing\n- Schema (database + tables) is created automatically on first\n ingest via idempotent DDL\n\nNew files (external-service-impl/rest/.../protocol/otlp/v1/):\n- OtlpTracesResource/MetricsResource/LogsResource: JAX-RS endpoints\n at /rest/v1/otlp/v1/{traces,metrics,logs}\n- OtlpService: singleton managing per-database sessions and schema\n- OtlpSchemaInitializer: idempotent CREATE DATABASE/TABLE DDL\n- OtlpIngestor + OtlpTableBatch: column-major batch -\u003e InsertTablet\n- OtlpTracesConverter/MetricsConverter/LogsConverter: OTLP -\u003e rows\n- OtlpConverter: timestamp precision, hex encoding, attribute helpers\n- OtlpHttp: protobuf/JSON request parsing and response rendering\n\nModified files:\n- rest/pom.xml: added opentelemetry-proto + protobuf-java-util deps\n- AuthorizationFilter: bypass auth for /rest/v1/otlp/ paths\n- IoTDBRestServiceConfig/Descriptor: added otlp_username/password\n- iotdb-system.properties.template: documented OTLP config section\n", "tree_diff": [ { "type": "modify", "old_id":
