Hi Shawn,

Look at CacheConfiguration.setWriteBehindEnabled [1] and related methods.
Does it meets your needs?

Shawn,

If it's a standalone node, you can just terminate the process. There is a
shutdown hook that will gracefully stop the node. For example, kill command
(without -9) will do the job.

For embedded node call Ignition.stop().
