release_notes_340.html |
The fourth minor release of Ditto 3.x, Eclipse Ditto version 3.4.0 is here.
This release is completely IP (intellectual property) checked by the Eclipse Foundation meaning that project code as well as all used dependencies were "[...] reviewed to ensure that the copyrights expressed are correct, licensing is valid and compatible, and that other issues have been uncovered and properly investigated."
Compared to the latest release 3.3.6, no features were added. This release focuses only on swapping the Akka framework (because of its switch of license to BSL License after Akka v2.6.x) with its fork Apache Pekko which is Apache 2.0 licensed.
To migrate a running system with live data there are few configurations that should be overridden with Java system properties in the following services.
Policies:
* -Dpekko-contrib-mongodb-persistence-policies-journal.overrides.metadata-index=akka_persistence_metadata_pid
* -Dpekko-contrib-mongodb-persistence-policies-journal-read.overrides.metadata-index=akka_persistence_metadata_pidThings:
* -Dpekko-contrib-mongodb-persistence-things-journal.overrides.metadata-index=akka_persistence_metadata_pid
* -Dpekko-contrib-mongodb-persistence-things-journal-read.overrides.metadata-index=akka_persistence_metadata_pidConnectivity:
* -Dpekko-contrib-mongodb-persistence-connection-journal.overrides.metadata-index=akka_persistence_metadata_pid
* -Dpekko-contrib-mongodb-persistence-connection-journal-read.overrides.metadata-index=akka_persistence_metadata_pid
* -Dpekko-contrib-mongodb-persistence-connection-remember-journal.overrides.metadata-index=akka_persistence_metadata_pidAnd also a full cluster recreate is required, rolling update is not supported as there are changes in the management urls and ports.
Other than that the transition should be smooth.
