Hello all,
yesterday we were doing a performance testing of our metadata DB that is built on top of a mutli region FDB and as we ramped after 20mins of stability around 330K QPS reads to 350K QPS reads the GRV latency started to spike on some proxy both for p50 and p99:
As you can see not all the GRV proxy saw an increase only 4 of them (50%).
Do we have any idea why this would occur ?
