# docker-dev/docker-compose.questdb.yml — optional QuestDB fixture for the QuestDB historian backend (#666).
#
# Up (touches ONLY the questdb service; it has no depends_on, and --no-deps makes that explicit):
#   docker compose -f docker-dev/docker-compose.yml -f docker-dev/docker-compose.questdb.yml up -d --no-deps questdb
#
# Image pinned by the T0 spike (docs/plans/2026-10-10-questdb-spike.md): questdb/questdb:10.0.1,
# pushed to Docker Hub 2026-08-24 (≥ 2 weeks before 2026-10-10; ≥ 8.2.3, the first release with table TTL).
# The image ships /usr/bin/curl, so the healthcheck uses it against the min-HTTP health endpoint on :9003.
