Apache DirectMemory is a multi layered cache implementation featuring off-heap memory management (a-la BigMemory) to enable efficient handling of a large number of java objects without affecting jvm garbage collection performance

Disclaimer

Apache DirectMemory is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

You can view our current incubation status for more details.
