GridGain 8.7.11 Release Notes

What’s New in This Release

This release includes a number of critical bugfixes.

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 ignite-ml module may not work correctly when used with Hadoop files models because of missing dependencies. If you experience issues, you can try adding the following libraries to the $IGNITE_HOME/libs directory:

  • We don’t recommend configuring caches with ATOMIC and TRANSACTIONAL atomicity modes within one cache group. Such configurations will be forbidden in future releases.

  • This release does not include the following dependencies:

    This can affect the functionality of CacheHibernateStore when GridGain is launched on Java 9+. If you experience exceptions related to missing dependencies, try adding the above mentioned libraries to $IGNITE_HOME/libs.

  • In this release, the failure handler will not print out the thread dump when an error is detected. In the previous versions, thread dumps were printed out by default. If you want to enable the old behavior, set the following system property:

    -DIGNITE_DUMP_THREADS_ON_FAILURE=true

    The old behavior is planned to be restored in the next version.

Fixed Issues

GridGain Community Edition Changes

GG-27116

Atomic Caches

Fixed atomic caches partitions desync caused by message reordering.

GG-26746

Binary Objects

Fixed an issue where an enum field of a BinaryObject could not be deserialized.

GG-26733

Diagnostics & Failure Handling

Added throttling for thread dump generation in the failure handler to prevent stop-the-world pauses.

GG-27037

Platforms & Thin Clients

Improved serialization performance for DateTime and other ISerializable types.

GG-22162

Rebalance

GridGain will now print all partitions that will be evicted with the eviction reason to the log.

GG-27121

Rebalance

Fixed exception caused by incorrect WAL reservation leading to a historical rebalance failure.

GG-27197

Security

Updated several dependencies to address the vulnerabilities reported by npm audit.

GG-27038

Security

The "javax.net.ssl.keyStoreProvider" property is now used to specify the default SSL key store provider.

GG-27058

SQL

Fixed an issue where the SQL MERGE INTO command fails when executed from a client node.

GG-24263

SQL

Optimized the deletion procedure for large SQL indexes. Deletion of a large index blocked the checkpoining operations and caused other operations to wait until the deletion is completed. Now large index deletion does not delay checkpoining.

GG-22560

SQL

Added support for SQL queries disk offloading. If a query consumes too much memory, it can be offloaded to disk in order to prevent out of memory error.

GG-26632

SQL

JDBC thin driver: SSL cipher suites can now be configured via the 'sslCipherSuites' parameter.

GG-27193

Storage Engine

Fixed an invalid assertion triggered by an intensive rebalancing leading to node crash.

GG-27150

Storage Engine

Fixed a possible IgniteOutOfMemoryException when a large cache in a cache group is destroyed

GG-26754

Thin Clients

Added an option to configure query timeout for thin clients.

GG-26922

Transactions

Fixed an NPE on transaction start which could cause partition desynchronization for the partitions that were evicted and assigned to the same node again.

GG-26858

Transactions

Performance improvement for transactional caches in PRIMARY_SYNC mode.

GridGain Enterprise Edition Changes

GG-26947

Data Replication

Fixed an issue where a server node configured as a sender did not replicate some data due to errors.

GG-26494

Data Replication

Fixed the compatibility issue introduced in version 8.7.8, where a custom implementation of DrSenderStore led to a compilation error.

GG-26487

Data Replication

Fixed incorrect DrFsStore size calculation.
