GridGain 8.7.10 Release Notes

What’s New in This Release

This release includes a new feature and a number of bug fixes/enhancements.

New Feature: @DurableStore annotation

Custom implementations of the sender node storage can now be annotated with the @DurableStore annotation to tell GridGain that the storage persists data and can survive restarts. When a sender node with a durable storage goes down, the replication process will not be stopped. The process will wait for the storage to be available again. Refer to the Sender storage documentation for details.

Installation and Upgrade Information

See the Rolling Upgrades page for information about how to perform automated upgrades and for details about version compatibility.

Known Issues

The public interface of DrSenderStore has been changed compared to version 8.7.8. If you use a custom implementation of this interface, do not upgrade to this version of the product. The old interface will be restored in a future release.
