# Meridian TSDB — Microservices Docker Compose
#
# Topology:
#   gateway (1)     — public API + dashboard + WebSocket
#   ingestor (2)    — TCP ingestion + hash-sharded writes
#   storage (3)     — TSDB engine, WAL, compression
#   querier (1)     — PromQL parsing, fan-out to storage
#   compactor (1)   — retention enforcement
#   simulator (1)   — metric generator
