# BullMQ Valkey Benchmark - Docker Compose
# Runs Valkey 7.2, 8.1, and 9.0 simultaneously on different ports.
#
# Usage:
#   docker compose up -d
#   docker compose down -v   # cleanup
#
# Default config (single-threaded) - matches typical Redis usage.
# For multi-threaded benchmarks, use the io-threads profile:
#   docker compose --profile io-threads up -d
