Description of PR

When using triggers to update tables in MySQL, the Table Map events may be out of order with the corresponding Write Rows events for those tables. This PR keeps a temporary map of table IDs to cache keys in order to retrieve the correct table information during Write Rows processing.

I've successfully compiled it on JDK 8 and I can confirm that it does fix the issue, it would be great if this change could make it into the next stable version.

Hey @mattyb149 - can you rebase against the main branch? Happy to get this in. I recently reviewed another PR related to this processor.

We're marking this PR as stale due to lack of updates in the past few months. If after another couple of weeks the stale label has not been removed this PR will be closed. This stale marker and eventual auto close does not indicate a judgement of the PR just lack of reviewer bandwidth and helps us keep the PR queue more manageable. If you would like this PR re-opened you can do so and a committer can remove the stale tag. Or you can open a new PR. Try to help review other PRs to increase PR review bandwidth which in turn helps yours.

There are two more issues opened about this now:

• https://issues.apache.org/jira/browse/NIFI-6914
• https://issues.apache.org/jira/browse/NIFI-7252

This issue is drastically impacting my organization's ability to utilize NiFi for synchronizing changes from an older legacy system into our new one. Any way this PR can be re-opened or reviewed? @mattyb149 @pvillard31
