Adds ``docker-compose-mysql.yml``, a compose-override file that swaps the default Postgres metadata DB for MySQL 8 with one extra ``-f`` flag: docker compose -f docker-compose.yml -f docker-compose-mysql.yml up Useful for evaluating dialect-specific behaviour (e.g., the runtime cost of DDL migrations on a deployment whose production metadata DB is MySQL — the question raised by review feedback on this PR). Mirrors the connection settings used by CI's ``test-mysql`` shard: ``mysql+mysqldb`` dialect, charset ``utf8mb4`` with binary_prefix. Host port defaults to 13306 (configurable via ``DATABASE_PORT_MYSQL``) to avoid colliding with a native MySQL install on 3306. A separate volume (``db_home_mysql``) keeps MySQL data isolated from the Postgres ``db_home`` volume, so switching between the two with ``-f`` flag toggles doesn't corrupt either side. The Postgres-specific init scripts under ``docker/docker-entrypoint-initdb.d/`` are not mounted on the MySQL service (they are postgres-only). Examples / cypress fixtures still load via ``superset-init``'s post-startup steps, which run ``superset load-examples`` against whichever metadata DB is in use.

# 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.
