# 3-node tidalDB cluster for local testing.
#
# Starts one leader (us-east) and two followers (eu-west, ap-south).
# WAL segments are replicated over TCP between the replication ports.
#
# Usage:
#   docker compose -f docker/docker-compose.cluster.yml up --build
#
# Health:
#   curl http://localhost:9400/health   # us-east (leader)
#   curl http://localhost:9401/health   # eu-west (follower)
#   curl http://localhost:9402/health   # ap-south (follower)
