Installing the JNA on RHEL or CentOS Systems
Installing JNA can improve Cassandra memory usage.
Installing JNA can improve Cassandra memory usage. When installed and configured, Linux does not swap out the JVM, and thus avoids related performance issues. The latest version is recommended.
Prerequisites
- Cassandra requires JNA 3.2.7 or later. Some Yum repositories may provide earlier versions.
- EPEL (Extra Packages for Enterprise Linux). See Installing EPEL.
