GridGain 8.7.5 Release Notes
What’s New in This Release
Introduction
This maintenance release includes many bug fixes, updates, and improvements to GridGain. In addition to the Fixed Issues, this release includes:
-
Added support for redeploying services on the fly.
-
Added events on cluster activation and deactivation.
-
Added JMX ability to exclude nodes from topology.
-
Added support of JAR files to
UriDeploymentSpi
. -
Updated Cassandra Store Driver version to 3.2
-
Better Java 11 support.
-
Several improvements and fixes for Web Console.
-
Improved performance and stability (memory leak fixes, fixes for SQL, indexes, etc.)
Changes in Behavior
Services Redeployment and JAR File Support
Now you can redeploy services on the fly (without having to restart the node) via DeploymentSpi.
If you have a service in a cluster and you want to update its implementation:
-
Update the JAR file(s) in the repository where the service is stored (pointed to by your
UriDeploymentSpi
configuration’suriList
property). -
Call the
services().cancel()
method to stop the service. -
Redeploy the service.
This is the same process currently used to redeploy tasks.
Fixed: Dynamic Changes to Cache Configurations (IGNITE-11541)
Prior to version 8.7.5, if you had a cache configured via XML configuration and changed it dynamically with a DDL statement (for example, alter a table or create/drop indexes), restarting the node would cause the cache to load its configuration from the XML configuration, ignoring the changes made dynamically.
If you have changed a cache configuration dynamically and have to restart a node, there are a couple of workarounds to the issue described above:
Remove the cache configuration from the configuration file before restarting the node. In this case the cache configuration will be loaded from the metadata. Change the XML configuration the same way you changed the cache dynamically. For example, if you dropped a column, remove that column from the cache configuration.
Beginning in version 8.7.5, changes made dynamically will persist after a node restart. If you want to keep the old behavior (i.e. always load static cache configuration after a restart), add the following property to the node’s startup command:
-DIGNITE_KEEP_STATIC_CACHE_CONFIGURATION=true
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
GG-18739 |
Persistence |
If you have enabled WAL compaction and also disabled WAL archiving, the following error message is written to the log on node startup: "Compression of WAL segment was skipped due to unexpected error". You can safely ignore this error message (the issue will be addressed in an upcoming release). |
