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 double
writing Snapshot fields for H2 stores adds considerable overhead to our
snapshot creation time.
Snapshots are also written as backups, and many operators choose to process
backups offline for analytics, rather than query the live scheduler (due to not
being able to scale reads horizontally). So this allows operators to
enable/disable the hydrated fields as needed.

Testing (updated)

./gradlew test
Applied this to an internal test cluster with the update hydration disabled and
verified snapshots and backups and failover.
Thanks,
