# Three-node YantrikDB cluster — example for local testing.
#
# Two voters + one witness, all on one machine via docker-compose.
# For production, run each container on a separate host so a single
# host failure doesn't take down quorum.
#
# Usage:
#   YANTRIKDB_CLUSTER_SECRET=$(openssl rand -hex 32) docker compose up
#
# Then connect from yql:
#   yql --host localhost -p 17438 -t $YANTRIKDB_CLUSTER_SECRET
