GridGain 8.7.25 Release Notes

Fixed Issues

Community Edition Changes

GG-30463

Atomic Cache

Reduced memory consumption when no MVCC caches are configured in the cluster

GG-30311

Continuous Queries

Continuous queries are no longer deployed to client nodes, since client nodes don’t store data.

GG-30536

Control Center Agent

Control Center agent now prints out a connection link as a result of token generation for convenience

GG-30229

Control Center Agent

Control Center agent is no longer required to be present on all cluster nodes. The cluster can connect to Control Center when at least one node has Control Center Agent enabled. The nodes without the Control Center agent will not report metrics.

GG-30234

Discovery

Updated Zookeeper dependencies: Netty to version 4.1.51.Final, log4j was excluded.

GG-29682

General

Fixed a class loading exception when the package name started with 'class'.

GG-28939

Integrations

Fixed an issue when default fetch size was used for data preloading for read-through cache instead of the size configured in JDBC dialect.

GG-30456

Metrics & Monitoring

Added metrics that provide information about the progress of index rebuild operations.

GG-29934

SQL

Fixed an issue where a primary key index contained fields in an incorrect order.

GG-28601

SQL

Introduced a mode of executing UPDATE queries in which GridGain updates the records on the nodes where they are stored instead of fetching the records to the node that initiates the query. This mode was previously available for JDBC/ODBC connections, but is now available for the queries executed via SqlFieldsQuery as well. See the SqlFieldsQuery.setSkipReducerOnUpdate(boolean) method description for details.

GG-29950

SQL

Fixed an issue when a suboptimal index was chosen for a query with an ORDER BY expression.

GG-30341

Storage Engine

Fixed an issue that could cause long pauses when speed-based write throttling was used.

GG-28146

Storage Engine

Added a BinaryObject method that allows you to perform unmarshalling with a custom classloader.

Enterprise Edition Changes

GG-30203

Data Replication

Data Replication: Added an example with authorization via SSL certificates.

GG-30524

Data Replication

The path to a keystore in SslContextFactory can now point to a classpath location. Previously, it was resolved only as a file system location.

Ultimate Edition Changes

GG-30358

Snapshot utility

Snapshot utility is now able to connect to client nodes.

GG-28818

Snapshot utility

Snapshot utility: added verbose mode.

GG-28121

Snapshots & PITR

Added the ability to add a prefix to the snapshot directory when creating snapshots programmatically. You can pass the prefix as an argument to the constructor of SnapshotCreateParams.

Known Limitations

If you are upgrading from version 8.7.20 or earlier, you must take into account an incompatibility related to Jetty configuration, which was introduced in GridGain 8.7.21.

Your setup may be affected if:

  • You’re using the ignite-rest-http module (e.g. to connect to GridGain Web Console)

  • You have a custom Jetty configuration that enables SSL for REST

  • Your Jetty configuration uses the org.eclipse.jetty.util.ssl.SslContextFactory class

  • The keystore specified in the Jetty configuration contains both the CA certificate and the private certificate

In this case, after starting the new version, you’ll see an error similar to:

java.lang.IllegalStateException: KeyStores with multiple certificates are not supported on the base class
org.eclipse.jetty.util.ssl.SslContextFactory. (Use org.eclipse.jetty.util.ssl.SslContextFactory$Server
or org.eclipse.jetty.util.ssl.SslContextFactory$Client instead)

To workaround this issue, you need to alter the Jetty configuration to use org.eclipse.jetty.util.ssl.SslContextFactory$Server or org.eclipse.jetty.util.ssl.SslContextFactory$Client. For a configuration example, see Client Certificate Authentication.
