khepri_mnesia_migration 0.2.1

At this point, khepri_mnesia_migration should be considered Alpha and not production ready. The API will likely evolve and future releases will likely introduce breaking changes. The goal of this release is to make it easy for anyone to try it and possibly give feedback.

What's new in khepri_mnesia_migration 0.2.1

This release contains mostly bug fixes and internal improvements, following
more extensive testing in RabbitMQ.

• is_migration_finished/{1,2} returns a meaningful return value even if the Khepri store is stopped (#4).
• rollback/2 waits for the Khepri projection to be updated before returning (#5). This makes sure is_migration_finished/2 will return false immediately after a rollback.
• Correctly handle a no_exists abort reason returned by the Mnesia function in mnesia_to_khepri:handle_fallback/4 (#6).
• Protect against infinite loop in mnesia_to_khepri:handle_fallback/4 (#7).
• Check record validity before running the mnesia_to_khepri callback module's copy_to_khepri/3 function (#8).
