GridGain 8.8.24 Release Notes
New Features
Native AOT Support
Known Issues
Complex SQL Operation With IN Operator Working Incorrectly
In GridGain 8.8.24, complex SQL operations that evaluate index key prefix and index key suffix in the same operation will return duplicate values for non-aggregate functions, or incorrect values for aggregate functions. Here is the example of the condition that can trigger the issue for index with a, b, c columns:
a=X AND c in (Y, Z)
If you use similar conditions in your environment, avoid updating to GridGain 8.8.24. An emergency 8.8.25-p1 patch release is scheduled soon. If you already use it and encounter the issue, update to GridGain 8.8.25-p1 version as soon as possible to fix the issue.

Known Limitations
Jetty Configuration Incompatibility in GridGain 8.7.21 and Later
If you are upgrading from version 8.7.20 or earlier, consider an incompatibility issue related to Jetty configuration introduced in GridGain 8.7.21.
Your setup may be affected if:
-
You use the
ignite-rest-httpmodule (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.SslContextFactoryclass -
The keystore specified in the Jetty configuration contains both the CA certificate and the private certificate
In this case, after starting a new version, an exception is thrown with an error message similar to the following:
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, alter the Jetty configuration to use org.eclipse.jetty.util.ssl.SslContextFactory$Server or org.eclipse.jetty.util.ssl.SslContextFactory$Client.
See the configuration example at the Client Certificate Authentication page.
Default rebalanceThreadPoolSize in GridGain 8.7.26 and Later
In GridGain 8.7.26, the default value of the property IgniteConfiguration.rebalanceThreadPoolSize changed from 1 to min(4, number of CPU / 4).
It may cause a compatibility issue under the following conditions:
-
When a Rolling Upgrade is performed
-
The upgrade is performed from 8.5.7 version (or earlier) to 8.5.x or from 8.7.3 (or earlier) to 8.7.x
-
The server nodes have at least 8 CPU cores
-
The nodes configuration does not have the property
IgniteConfiguration.rebalanceThreadPoolSize, so the default value is used
In this case, an exception is thrown with an error message similar to the following:
сlass org.apache.ignite.IgniteException: Rebalance configuration mismatch (fix configuration or set -DIGNITE_SKIP_CONFIGURATION_CONSISTENCY_CHECK=true system property).
Different values of such parameter may lead to rebalance process instability and hanging. [rmtNodeId=5fc58fb7-209d-489a-8034-0127a81abed6, locRebalanceThreadPoolSize = 4, rmtRebalanceThreadPoolSize = 1]To workaround this issue, change the configuration of the server nodes to rebalanceThreadPoolSize=1 so that it matches
the previous default configuration. For example:
<bean class="org.apache.ignite.configuration.IgniteConfiguration">
<property name="rebalanceThreadPoolSize" value="1"/>
<!-- The rest of the configuration goes here -->
</bean>Jetty Doesn’t Accept Incorrect Configuration in GridGain 8.7.31 and Later
In GridGain 8.7.31 Jetty was upgraded to 9.4.33. Starting that version, Jetty has more strict validation of the provided configuration files. Before that version, an incorrectly spelled property in the configuration file had no effect. Starting this version, errors in the configuration will lead to an error on start.
Your setup may be affected if:
-
You use the
ignite-rest-httpmodule (e.g. to connect to GridGain Web Console) -
You have a custom Jetty configuration for REST
-
The custom configuration has errors in it
You will need to fix the custom Jetty configuration before upgrading.
ignite.sh No Longer Enables Remote JMX by Default in GridGain 8.7.31 and Later
Starting from 8.7.31 version, GridGain no longer attempts to automatically enable the remote JMX. Default settings are known to cause issues if customized (for example, secure the connection). Also, in most cases, remote JMX is not required since many tools use local JMX connections (not using TCP).
Your setup may be affected if:
-
You start GridGain nodes via
ignite.shscript -
You connect to GridGain nodes' JMX interface remotely over TCP using the default configuration
To continue using remote JMX, you need to manually specify the required JMX settings. Please see the example below. Note that you don’t need remote JMX if you use a local connection, such as connecting JConsole to a GridGain process on the same host.
export JVM_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=33333 \
-Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false"
bin/ignite.sh.NET: GridGain Nuget Package Misses GridGain.Ignite Jars in 8.8.17
Set <PrivateAssets>None</PrivateAssets> for the GridGain.Ignite dependency in GridGain project, so that jars from there are included.
