GridGain 8.9.25 Release Notes

Overview

GridGain 8.9.25 is a maintenance release focused on improving stability and providing improved logging information.

Major Changes

Required Uniform Binary Object Sorting

Starting with this release, all nodes, thick and thin clients must have the automatic binary object sorting set to the same value. You can configure this by setting the IGNITE_BINARY_SORT_OBJECT_FIELDS VM property (false by default). For most clusters, this is already consistent and the update does not require additional actions.

For clusters where this is not the case, manually set the IGNITE_BINARY_SORT_OBJECT_FIELDS to the same value across the cluster prior to updating to this version.

Installation and Upgrade Information

See the Rolling Upgrades page for information about how to perform automated upgrades and for details about version compatibility.

Migrating from GridGain 8.9.17 or Earlier With Java 8

Starting GridGain 8.9.18, GridGain uses Lucene 9 by default. As Lucene 9 requires Java 11, it will be impossible to run GridGain on Java 8 with default configuration.

To continue using Java 8 when migrating to GridGain 8.9.18 or later, replace the {GRIDGAIN_HOME}/libs/ignite-lucene-9 folder with {GRIDGAIN_HOME}/libs/optional/ignite-lucene-8.

Migrating From GridGain 8.9.0

GridGain 8.9.1 introduced a large number of changes in default configuration values. Your setup may be affected if you are using default configuration.

When migrating to GridGain 8.9.25, make sure to check Changed Default Values in GridGain 8.9.1 and Later section for any parameters you need to change.

Migrating From GridGain 8.X

When migrating from GridGain 8.8 to GridGain 8.9, no special actions are required for core functionality migration. By using rolling upgrades, you can update from any GridGain version listed below. You may need to perform minor configuration changes to ensure stability post migration.

If you are using GridGain Enterprise or Ultimate, the COPY command was reworked as described in the [COPY Command Changes] section. The syntax for working with CSV remains the same, but the path is now calculated on the node and the client. This change does not affect GridGain Community edition.

To disable this behavior and use the old copy command, pass the disabledFeatures=SERVER_BULK_LOAD parameter in the JDBC connection command:
```
jdbc:ignite:thin://127.0.0.1/?disabledFeatures=SERVER_BULK_LOAD
```
If you are using one of the optional modules listed in the [Removed Modules] section, they will continue to work, but compatibility and stability on GridGain 8.9 is not guaranteed. Consider using the alternatives:
- Visor CMD and GUI can be replaced by GridGain Control Center.
- The spark module can be replaced by the Spark Ignite Extension.
If you are using default values in your configuration, you may need to set them manually to keep you cluster working the same way as in previous versions. Make sure to check Changed Default Values in GridGain 8.9.1 and Later section for any parameters you need to change.

Known Limitations

Java 8 Support in GridGain 8.9.18 and Later

Starting GridGain 8.9.18, GridGain uses Lucene 9 by default. As Lucene 9 requires Java 11, it will be impossible to run GridGain on Java 8 with default configuration.

We recommend switching to Java 11 or later before updating to GridGain 8.9.18 or later.

To continue using Java 8, replace the {GRIDGAIN_HOME}/libs/ignite-lucene-9 folder with {GRIDGAIN_HOME}/libs/optional/ignite-lucene-8.

Unsupported Features When Using Java 8 in GridGain 8.9.17

In GridGain 8.9.17, full text search is not supported when GridGain is running on Java 8. The new vector search feature requires using Java 11.

Additionally, GridGain 8.9.16 or earlier automatically created full text indexes for caches with string values, which may cause issues for working with the cache while using Java 8. To avoid this behavior, set the sql.disableCreateLuceneIndexForStringValueType property to true. If such index is already built for a cache with persistence, contact our support team for assistance with removing it.

We recommend switching to Java 11 or later before updating to GridGain 8.9.17 if you plan to use these features.

Changed Permissions for Control Center Agent in GridGain 8.9.4 and Later

GridGain 8.9.4 introduced stricter permissions checking for Control Center Agent. When running secured clusters, some actions that previously were available without permissions, will now require additional permissions.

Before updating, make sure to provide the required permissions, otherwise some actions may become unavailable.

New TRACING_CONFIGURATION_UPDATE Permission in GridGain 8.9.2 and Later

GridGain 8.9.2 introduced the TRACING_CONFIGURATION_UPDATE permission. If you were using security on a cluster before updating to this version, make sure that you provide the permissions to control utilities or users who need to update cluster permissions. Otherwise, they will not be able to update

Changed Default Values in GridGain 8.9.1 and Later

If you are updating from GridGain 8.8.X or 8.9.0, a large number of default values have been changed.

These changes may affect the stability or performance of your cluster if you are using default values.

We recommend checking the list below to make sure the changes do not have an adverse effect, and setting the value manually if necessary.

Service processor now use event-driven implementation by default. You can keep the old behavior by setting the IGNITE_EVENT_DRIVEN_SERVICE_PROCESSOR_ENABLE property to false. Make sure that all nodes in the cluster are set to the same value. See Services documentation for more information.
Data region metrics are now enabled by default. This may have a minor (within 2%) adverse effect on performance. You can keep the old behavior by setting the DataRegionConfiguration.metricsEnabled value to false.
Data storage metrics are now enabled by default. This may have a minor (within 2%) adverse effect on performance. You can keep the old behavior by setting the DataStorageConfiguration.metricsEnabled value to false.
TcpCommunicationSpi communication protocol now has a limit of 4096 messages for the outgoing messages queue by default.
Atomic operations are now not allowed in transactions by default. You can keep the old behavior by setting the IGNITE_ALLOW_ATOMIC_OPS_IN_TX value to true.
Logs are now in verbose mode by default. You can use the -q command line argument in the ignite.sh script to keep current log behavior.
SQL queries are now loaded lazily by default. This reduces memory consumption on medium and large queries and potentially improves garbage collection performance. You can keep the old behavior by setting the SqlFieldsQuery.setLazy(false).
Cache entries are now read from primary partitions by default, even if an entry is available on the node in a backup partition. This may have a minor performance impact, but significantly increases cluster stability. You can keep the old behavior by setting the readFromBackup property to true.
Partition map exchange transactions now time out after 1 minute instead of 0 (infinite) by default. You can keep the old timeout by setting the TX_TIMEOUT_ON_PARTITION_MAP_EXCHANGE setting to 0.
Data streamer now overwrites entries by default. You can keep the old behavior by setting the stmr.allowOverwrite property to false.
TCP discovery now uses static IP finder TcpDiscoveryVmIpFinder by default. To keep the old behavior, set the IP finder to use multicast IP finder.
Checkpointing process now starts upon reaching 75% of minWalArchiveSize instead of 25%. You can keep the old behavior by setting the IGNITE_CHECKPOINT_TRIGGER_ARCHIVE_SIZE_PERCENTAGE system variable to 0.25.
