-- SQL Data Source Cache uses Plasma as a node-level external cache service, the benefit of using external cache is data could be shared across process boundaries.  [Plasma](http://arrow.apache.org/blog/2017/08/08/plasma-in-memory-object-store/) is a high-performance shared-memory object store and a component of [Apache Arrow](https://github.com/apache/arrow). We have modified Plasma to support PMem, and make it open source on [oap-project-Arrow](https://github.com/oap-project/arrow/tree/arrow-4.0.0-oap-1.1.1) repo. If you have finished [OAP Installation Guide](OAP-Installation-Guide.md), Plasma will be automatically installed and then you just need copy `arrow-plasma-4.0.0.jar` to `$SPARK_HOME/jars`. For manual building and installation steps you can refer to [Plasma installation](./Developer-Guide.md#Plasma-installation).
