Berkeley DB Java Edition 3.1.0 Available
Berkeley DB Java Edition (JE) 3.1.0 is now available for download. It is available in both zip and tar.gz packages.
Features for this release are:
- Direct Persistence Layer (DPL) is GA and the Class Evolution feature is available.
A new method, com.sleepycat.je.Database.count(), which has been
optimized to execute faster than the count obtained from a database
scan.
A new method, EnvironmentConfig.setExceptionListener() provides a
notification mechanism for asynchronous exceptions thrown by JE daemon
threads.
Added a new Environment configuration parameter: je.adler32.chunkSize
to work around JVM memory allocation issues in some versions of Java
1.5 and earlier.- Several bug fixes including one that resulted in poor cache eviction management, and
therefore poor performance when there is a high level of log cleaning
in conjunction with a high level of cache eviction.
Full details are in the
release notes and change log.
