Chapter 1. Data Grid 8 upgrade notes Review the details in this section before upgrading from one Data Grid 8 version to another. 1.1. Upgrading to Data Grid 8.5 Read the following information to ensure a successful upgrade from versions of Data Grid 8 to 8.5. Removals The Kryo and Protostuff marshallers have been removed. Extended statistics module has been removed. JCache CDI is no longer supported. Spring 5.x and Spring Boot 2.x are no longer supported. Red Hat JBoss EAP modules are no longer provided. Change of package for classes The following classes have been moved to different packages: org.infinispan.util.TimeoutException has been moved to org.infinispan.commons.TimeoutException org.infinispan.util.concurrent.IsolationLevel has been moved to org.infinispan.configuration.IsolationLevel Classes, methods, and properties removal The following methods and properties have been removed: All: Parsing of configuration files with schema < 10.0 Commons: Start.priority and Stop.priority Core: AdvancedCache.with(ClassLoader) , AdvancedCache.getEvictionManager() , AdvancedCache.getAsyncInterceptorChain() , AdvancedCache.getComponentRegistry() Core: AnyScopeComponentFactory.construct(Class) Core: Cache.getListeners() Core: ConfigurationBuilder.classLoader() , ConfigurationBuilder.customInterceptors() Core: DataRehashedEvent.getUnionConsistentHash() Core: EmbeddedCacheManager.getListeners() , EmbeddedCacheManager.getTransport() , EmbeddedCacheManager.removeCache(String) , EmbeddedCacheManager.getGlobalComponentRegistry() Core: FlagAffectedCommand.setFlags , FlagAffedctedCommand.addFlags , FlagAffectedCommand.hasFlag Core: IntCacheStream.filterKeySegments(Set<Integer>) Core: JMXStatisticsConfiguration Core: GlobalConfiguration.DEFAULT_MARSHALL_VERSION Core; LocalizedCacheTopology.getDistributionForSegment(int) Core: NamedComponentFactory Core: PersistenceUtil.loadAndStoreInDataContainer Core: TopologyChangedEvent.getConsistentHashAtStart() and TopologyChangedEvent.getConsistentHashAtEnd() Core: Transport.invokeRemotely() Transport.waitForView() Transport.backupRemotely() AbstractTransport Core: ValueMatcher.nonExistentEntryCanMatch Core: WriteCommand.updateStatusFromRemoteResponse Core: state transfer pool Counters: SyncStrongCounter and SyncWeakCounter Hot Rod client: org.infinispan.client.hotrod.marshall.ProtoStreamMarshaller Server and clients: keystore certificate password RocksDB Store: expiry queue size Remote Store: transport factory and maxIdle Metrics The JGroups and cross-site metrics names change when names-as-tags is set to true , where the cluster's name and the site's name are no longer present in the metrics name but as a tag. As an example, when you set names-as-tags to false , metrics are named based on the channel, resulting in multiple metrics for the same purpose: When you set names-as-tags to true , metrics are simplified, and cluster and site names appear as tags: SecurityManager Aligning with the deprecation for removal of the SecurityManager in Java Development Kit (JDK) 17, integration with a SecurityManager is no longer supported. Jakarta and Java EE Data Grid has been updated to use jakarta.* packages only. If you require the legacy javax.* packages, you should use Data Grid 8.4.x. The transitional *-jakarta jars, which included both jakarta.* and javax.* packages, have been removed. Hot Rod client defaults Data Grid introduced changes to the properties of the Hot Rod client. ssl_hostname_validation A new property, ssl_hostname_validation with a default value of true has been added. This property enables TLS hostname validation based on RFC 2818 . Additionally, setting the sni_host_name is now required when hostname validation is enabled. Table 1.1. Default property changes Property Data Grid 8.5 versions connect_timeout 2000 ms / 2 seconds 60000 ms / 60 seconds socket_timeout 2000 ms / 2 seconds 60000 ms / 60 seconds max_retries 3 10 min_evictable_idle_time 180000 ms / 3 minutes 1800000 ms / 30 minutes sasl_mechanism SCRAM-SHA-512 SCRAM-SHA-256 Search Data Grid 8.5 introduces the following changes to search. Indexing The property attribute has been removed. The auto-config attribute has been removed. The index attribute has been removed. Indexing annotations The Hibernate Search 5 annotations are no longer supported. @ProtoDoc annotation is now deprecated. Security The PrincipalRoleMapper now applies only to groups instead of both groups and user principals. Use the cache-manager.security.authorization.group-only-mapping=false configuration to use the old behavior. For more information about the PrincipalRoleMapper API, see Role and permission mappers . Scattered cache removal The scattered cache mode has been removed. Use distributed caches instead. For information about cache modes, see Cache modes . Global State By default, Data Grid will not start if a dangling lock file is found in the persistent global state indicating an unclean shutdown. You can change the default behavior by configuring the global state unclean-shutdown-action setting. For more information, see Global persistent location . Persistence The default value for availability-interval has been increased to 30 seconds. The default was 1 second. Soft-index file stores To calculate the number of segments, only the number of cache segments is used instead of using index segment configuration, as was done earlier. RESP endpoint Data Grid 8.5 introduces the following changes to the RESP endpoint: The RESP endpoint cache now requires the key storage media type to be application/octet-stream . You can apply default expiration to the cache configuration used by the RESP endpoint. Client listeners remove events propagation To support the changes around the new includeOldValue method on CacheEventConverter , client listeners remove events will now be propagated even if the event does not remove a value. Note Remove events do not include any values by default NearCache SPI update The NearCache SPI had an issue with concurrent updates wherein a stale entry could get stored in the near cache. NearCache SPI has been updated to address this issue. Upgrade from 8.1 at a minimum If you are upgrading from 8.0, you must first upgrade to 8.1. Persistent data in Data Grid 8.0 is not binary compatible with later versions. To overcome this incompatibility issue, Data Grid 8.2 and later automatically converts existing persistent cache stores from Data Grid 8.1 at cluster startup. However, Data Grid does not convert cache stores from Data Grid 8.0.
