# Microservices Architecture - Each agent runs as a separate container
#
# Benefits:
# - Independent scaling (scale graph-query separately from indexer)
# - Better resource isolation
# - Horizontal scaling with replicas
# - Easier debugging and monitoring per agent
#
# Usage:
#   docker compose up -d
#   docker compose up -d --scale graph-query-agent=3
