[GitHub] nifi issue #1240: NIFI-3039 Provenance Repository - Fix PurgeOldEvent and Ro...

Github user mosermw commented on the issue:

    https://github.com/apache/nifi/pull/1240
  
    I tested this a lot, and based on the conversation in the JIRA ticket, I adjusted the purge low water mark to 88%. This allows the prov_repo to purge old events quicker after a large spike in events, whereas before it could take a long time to bring the prov_repo back down to 90% usage.  It also doesn't delete too many events.  I also adjusted the rollover high water mark to 99%, which allows space for journals and indexes. This keeps prov_repo usage much closer to the nifi.provenance.repository.max.storage.size.
    +1 will merge.
