Github user markap14 commented on the issue: https://github.com/apache/nifi/pull/2416 The proposed solution does address the issue that was raised in NIFI-4774, but in doing so introduces a new issue of data loss. This is why I provided the solution that I did in the PR, as I believe that it addresses both of these issues. Again, I do not have a problem with making this new solution one that the user is able to opt out of, though. If you want to submit a PR that also incorporates your proposed solution into the MinimalLockingWirteAheadLog that is okay too and we can also review and incorporate that change as well.
