+# Compose override that swaps the default Postgres metadata DB for MySQL 8.
+# Useful for evaluating dialect-specific behaviour (e.g., DDL-migration
+# cost on a deployment whose production metadata DB is MySQL).
+#
+# Usage:
+#   docker compose -f docker-compose.yml -f docker-compose-mysql.yml up
+#   docker compose -f docker-compose.yml -f docker-compose-mysql.yml down
+#
+# To switch back to Postgres, just drop the second `-f` flag — the MySQL
+# data lives in a separate volume (`db_home_mysql`) so neither side is
+# corrupted by switching dialects.
+#
+# Notes:
+#   - Mirrors the connection settings used by CI's `test-mysql` shard:
+#     dialect ``mysql+mysqldb``, charset utf8mb4 with binary_prefix.
+#   - Host port 13306 (configurable via DATABASE_PORT_MYSQL) to avoid
+#     colliding with a native MySQL install on 3306.
+#   - The Postgres-specific init scripts under
+#     docker/docker-entrypoint-initdb.d/ are not mounted (they are
+#     postgres-only); examples / cypress fixtures still load via
+#     `superset-init`'s post-startup steps.
+
+# Shared environment override applied to every Superset-side service that
+# connects to the metadata DB. ``environment:`` takes precedence over the
+# values inherited from the env_file in docker-compose.yml.
