Major Releases

This page notes all enhancements and features that we have introduced to our major releases of the Axon Mongo Extension.

Release 4.5

• We introduced a dedicated sample project to the Mongo Extension. The sample is written in Kotlin and shows how to use the MongoEventStorageEngine and MongoTokenStore. For those interested, you can find the pull request here.

• Contributor erikrz provided an issue and pull request to allow the MongoTokenStore index to be automatically validated. Issue #51 marks the request, whereas #53 marks the pull request.

• The MongoTokenStore now implements the retrieveStorageIdentifier method, as of pull request #139. This change allows clustered environments, like Axon Server, to tell apart the Mongo Databases of Event Processors. This further benefits split, merge and release operations performed in a distributed environment.

We refer to the release notes for a complete list of all changes.

Release 4.4

• Issue #10 introduces support for Spring Boot Developer Tools.

• Contributor bjornharvold provided a pull request to update the MongoDB java driver to 4.0.3. For those interested in the adjustments, you can check them out here.

We refer to this page for a list of all changes.

Release 4.3

We did not introduce any significant changes other than updating the extension to use Axon Framework release 4.3.

Release 4.2

We did not introduce any significant changes other than updating the extension to use Axon Framework release 4.2.

Release 4.1

Contributor mwlynch introduced a small improvement on the MongoTokenStore and MongoEventStorageEngine. Namely, he removed the @PostConstruct annotation from the ensureIndexes() methods and moved the invocation to the constructor. For the specific changes, we refer to this pull request.

Release 4.0

We split off the Mongo logic from Axon Framework core into a dedicated repository. Next to that, it complies with Axon Framework's 4.0 release.
