How to put data in distributedMapCacheClientSrevice controller service or any other service for multiple host names in a one go only.

In My Application i am using detect duplicate processor and we having five node cluster so what is the best way to put data in distributed map cache in one go for all the servers since using one hostname entry in that service only makes wpes out the data if server is restarted.

In DistributeMapCacheServer we can define Persistence Directory value

If specified, the cache will be persisted in the given directory; if not specified, the cache will be in-memory only.

If we define persistence directory then NiFi will not wipes out the data if server is restarted.
