Chapter 14. Features and Functionality Deprecated in Data Grid 7.3

This release of Data Grid deprecates various features and functional components.

Deprecated functionality continues to be supported until Data Grid 7.x end of life. Deprecated functionality will not be supported in future major releases and is not recommended for new deployments.

Note

This information is current as of the time of writing. You can review all the deprecated code for the next major release with JDG-1978.

Hot Rod v1.x
Hot Rod protocol version 1.x will not be supported in the next major release.
RocksDB Replaces LevelDB Cache Store
As of this release, the LevelDB cache store is deprecated and replaced with the RocksDB cache store. If you have data stored in a LevelDB cache store, the RocksDB cache store converts it to the SST-based format on the first run.

RocksDB provides superior performance and reliability, especially in highly concurrent scenarios. Find out more about the RocksDB cache store in the documentation.

Compatibility Mode

Compatibility mode is deprecated and will be removed in the next major release. To access a cache from multiple endpoints, you should store data in binary format and configure the MediaType for keys and values. See the following topics for more information:

  • Protocol Interoperability

  • MediaType

    If you want to store data as unmarshalled objects, you should configure keys and values to store object content as follows: 

    <encoding>
   <key media-type="application/x-java-object"/>
   <value media-type="application/x-java-object"/>
</encoding>
Clustered Executor Replaces Distributed Executor API

Data Grid replaces Distributed Executor with Clustered Executor, which is a utility for executing arbitrary code in the cluster. See:

RemoteCache getBulk()
The getBulk() method is deprecated in the RemoteCache interface. See: org.infinispan.client.hotrod.RemoteCache.
Agroal PooledConnectionFactory Replaces c3p0/HikariCP JDBC PooledConnectionFactory
The JDBC PooledConnectionFactory provides connection pools that you configure with c3p0.properties and hikari.properties. In the next major release, Data Grid provides a PooledConnectionFactory that you configure only with an agroal compatible properties file. See Agroal project.
CLI Loader
infinispan-persistence-cli is now deprecated and will be removed in the next major version.
Deprecated Classes
  • org.infinispan.lifecycle.AbstractModuleLifecycle
  • org.infinispan.lifecycle.Lifecycle
Eager Near Caching Residual Code
Residual code artifacts for eager near caching functionality will be removed in the next major version.
