Synchronous migrations

tip

This is the default, and historic behaviour of Depot as of version 9.3.0

In this mode, Depot runs the migration process as part of the Dataset's Cloudformation deployment, using a lambda function to execute the migration process. A lambda function has a short start latency (typically < 1 second), and a maximum execution time of 15 minutes.

warning

If the migration process cannot be completed within 15 minutes, the lambda function will time out and the migration will fail. The failure of the migration process will fail the deployment, which will cause a rollback of the environment deployment.
