1.3.6. LevelDB Cache Store
JBoss Data Grid 6.2 features a new LevelDB cache store which provides high throughput in reads and writes to disk. This cache store is based on Google’s C++ LevelDB implementation with a JNI connector, and is available in both Library and Client-server modes.
The LevelDB cache store is the preferred option when a large number of entries are persisted locally on a node.
The LevelDB library and JNI connector are not part of the JBoss Data Grid 6.2 distribution.
To use the tested version, add the file
leveldbjni-all-1.7.jar from https://github.com/fusesource/leveldbjni to your JBoss Data Grid deployment.
1.3.6.1. LevelDB Tested Configurations

LevelDB is tested using JBoss Data Grid's Library and Remote Client-Server modes on:
- Red Hat Enterprise Linux 5 (32-bit and 64-bit) with the following JDKs:
- IBM JDK 1.6 and 1.7
- OpenJDK 1.6
- Oracle JDK 1.6 and 1.7
- Red Hat Enterprise Linux 6 (32-bit and 64-bit) with the following JDKs:
- IBM JDK 1.6 and 1.7
- OpenJDK 1.6 and 1.7
- Oracle JDK 1.6 and 1.7
Red Hat supports using LevelDB via this JNI connector as a Cache Store with Red Hat JBoss Data Grid 6.2, and will assist in diagnosing an issue with use of LevelDB with JBoss Data Grid. However, if the issue is determined to be with LevelDB or the JNI connector, Red Hat will be limited in how it can resolve the problem - Red Hat does not distribute, maintain, or patch LevelDB or the JNI connector with JBoss Data Grid 6.2.
