Review request for Aurora, Joshua Cohen, Santhosh Kumar Shanmugham, and Zameer
Manji.
Bugs: AURORA-1861
https://issues.apache.org/jira/browse/AURORA-1861
Repository: aurora
Description
-------
Motivation: Thanks to the mybatis query metrics we added, we found that the
redundant query I'm removing here currently adds 20s to the snapshot creation
time. This is an extra 20s unavailability every time we snapshot on our prod
clusters.
===
Avoid double writing job updates to the Scheduler Snapshot. This should be
low-risk because:
1) Job Updates have *never* had an in-memory store implementation.
2) They are also relatively new, so the chances of some old code processing job
updates from backups is fairly low?

Testing

./gradlew test
I'll apply this to one of our test clusters before merging to master too.
