• Circle CI Setup to run tests. Tests should spin up the databases in a container and tear down the environment cleanly.
• Upload containers of ModelBox server to Docker Hub
• Create a Docker Swarm template to run all the components locally for testing. Could be useful for the Circle CI environment as well.
• Remove re-bind calls in the sql storage code and move driver specific parameterized queries in driver code
• Create a new interface driverQueries to move the queries there instead of using the driverUtils interface
• Remove code which looks for duplicate error codes and surpasses errors, instead moving idempotency to queries for mysql. Postgres queries are already idempotent.
• Add possible values for various storage configuration in server config.toml so that it's documented in the config itself.
