# Spark + Paimon for integration tests: writes tables to a local volume
# so paimon-rust can read them (no MinIO/S3).
#
# Usage:
#   1. Generate test data (run once):
#        docker compose -f dev/docker-compose.yaml run --rm spark-paimon
#   2. Run read integration tests on the host:
#        PAIMON_TEST_WAREHOUSE=/tmp/paimon-warehouse cargo test -p paimon-integration-tests read_from_spark
#
# To re-provision: remove /tmp/paimon-warehouse and run step 1 again.

services:
  spark-paimon:
    build:
      context: ./spark
      dockerfile: Dockerfile
    volumes:
      # Bind warehouse to host so paimon-rust can read it
      - /tmp/paimon-warehouse:/tmp/paimon-warehouse
    # Run as root to avoid permission issues with mounted volumes
    user: root
    # Run provision script and exit (data remains in /tmp/paimon-warehouse).
    # Use full path: entrypoint exec does not have SPARK_HOME/bin in PATH.
