GridGain 8.7.22 Release Notes

New Features

Added commands to the control script to view, remove and update the binary types registered in the cluster.

Changes In Behavior

The "cache" and "query" rest commands will no longer use the "default" cache if the cacheName parameter is not specified.
The experimental IgniteConfiguration.environmentType property is replaced with TcpCommunicationSpi.forceClientToServerConnections, which has the same effect.

Fixed Issues

Community Edition Changes

GG-29764

Architecture

Removed the "default" cache from the "cache" and Query REST methods, which was used when the cacheName parameter was not set. The methods will return an error, "Failed to find mandatory parameter in request: cacheName", if the cache name is not specified.

GG-29031

Architecture

Introduced a graceful shutdown policy that prevents data loss on node shutdown.

GG-29690

Communication

The experimental "environmentType" property was replaced with TcpCommunicationSpi.forceClientToServerConnections. Fixed an issue where a deadlock could occur in the TcpCommunicationSpi idle connection worker.

GG-29877

Control Center Agent

SQL

Fixed an issue where the "name" property of the QuerySqlField annotation was not taken into account when verifying field name uniqueness.

GG-29781

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.
