Driver

Using Flyway with MongoDB Native Connectors

• If you are using javascript migrations then you'll need mongosh to be installed.
• There is a tutorial available here.

Observations

AWS DocumentDB aims to be MongoDB compatible - as such we use the Flyway MongoDB infrastructure and can only verify that Flyway's verb testing works.

• We saw this error: MongoServerError: Retryable writes are not supported which was overcome by adding retrywrites=false to the connection string, See Functional differences: Amazon DocumentDB and MongoDB
• We had to set up an SSH tunnel to work on DocumentDB from outside of the AWS VPC
• TLS is enabled by default on DocumentDB and requires the Java Truststore to be set up to work with AWS.

Limitations

• Transactions are only available with JSON migrations (these use the API and not Mongosh)
