GridGain 8.5.14 Release Notes

GG-25988

Affinity and Baseline Topology

An issue with affinity history overflow that can lead to failed transactions has been fixed. This behavior can be observed in case of frequent topology change when nodes are joining and leaving cluster too often.

GG-26539

Atomic Cache

In case DataRegion is filled, user can get the IgniteOutOfMemory exception, even for remove operations. The release fixes this behaviour, and cache cleanup should no longer cause any issues.

GG-26475

Data Structures

Checkpoint throttling logic has been improved. In case of simultaneous rebalance and checkpoint process, checkpoint IO should be processed with the priority to decrease performance pressure from background tasks.

Scan query transformer can now be deployed using peer class loading in case if they are not deployed on cluster nodes.

GG-26272

Diagnostics & Failure Handling

Failure handler will now handle index build exceptions.

SQL

Log record level has been decreased form ERROR to INFO for SQL query cancel operation. It will prevent a significant number of log messages from being written in the logs in case of frequent cancel operations.
