flight_sql_server

flight_sql_service_impl

minimal FlightSQL protocol implementation

grpc_health_service

health check service for gRPC servers

http_gateway

pg_stats

periodic self-observability collector for the metadata Postgres’s pg_stat_* views Periodic self-observability collector for the metadata Postgres: samples the standard pg_stat_* catalog views (plus index/table sizes) and emits the readings as micromegas metrics through the process’s own tracing sink. This turns questions that today can only be answered by connecting to the DB (e.g. which indexes are dead weight) into hard evidence queryable via FlightSQL.

shared readiness probe logic (DB + blob, 1 s success cache)

shutdown

SIGTERM-driven graceful shutdown primitives shared by all services

sqlinfo

metadata about this implementation of FlightSQL

tonic_auth_interceptor
