+# 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=./dev/warehouse cargo test -p 
paimon-integration-tests read_from_spark
+#
+# To re-provision: remove dev/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 ./warehouse).
