signaldb

SignalDB Tempo API compatibility - implemented/stub endpoints, query flow, admin API, Grafana native plugin, and built-in Tempo datasource support. Use when working with HTTP API, Grafana integration, or query endpoints.

SignalDB architecture reference - FDAP stack, write/query data flow, service components, deployment models, and dual catalog system. Use when understanding how components fit together, data flow, or system design.

SignalDB crate map - workspace members, module locations within common/writer/querier/router crates, and key root files. Use when navigating the codebase, finding where code lives, or understanding module boundaries.

SignalDB multi-tenancy and authentication - tenant model, auth flow, isolation layers, slug-based naming, API keys, admin API, and CLI. Use when working with tenant isolation, authentication, API keys, or dataset management.

SignalDB configuration reference - all TOML sections, environment variables, database/discovery/storage/WAL/schema/auth/queue settings, and service ports. Use when working with configuration, environment variables, or TOML settings.

Step-by-step guide for adding a new signal type or table to SignalDB - schema definition, Flight schema, OTLP conversion, WAL operation, acceptor/writer/querier/router updates, and testing. Use when adding new signal types, metric types, or tables.

SignalDB development workflow - build, test, lint, format, run services, Docker, Grafana plugin, health checks, and semantic commits. Use when building, testing, running, or deploying SignalDB.

SignalDB documentation routing - where docs live, the audience taxonomy (users/operations/architecture/contributing), required frontmatter, and when a code change owes a doc update. Use when adding or editing documentation, deciding where a doc belongs, or settling doc debt after finishing a feature.

SignalDB Flight schemas and schema versioning - v1 wire format vs v2 storage format, schema inheritance, write-time transformations, traces/logs/metrics table schemas, and Flight RPC methods per service. Use when working with Arrow schemas, OTLP conversion, schema transforms, or Iceberg table schemas.

SignalDB service discovery - capability-based routing, ServiceBootstrap pattern, catalog schema, connection pooling, and heartbeat mechanism. Use when working with service registration, capability routing, or inter-service communication.

SignalDB storage layout - WAL directory structure, Iceberg catalog, object store paths, table types, segment lifecycle, and per-dataset storage overrides. Use when working with WAL, Iceberg tables, Parquet files, or storage configuration.
