> The Stats could be inconsistent and incomplete due to region servers going down, RPC
failures when committing Guidepost data to Stats table and the lack of retry and atomic operation.
The expected behavior from the Platform is “We need a strong guarantee that on stats write
there are sufficient retries and monitoring in place so that stats writes are resilient such
that we will not end up with inconsistent, partial or empty stats until the next run of UPDATE
STATISTICS”.
