Description
woq (write/obs/query) is a standard pattern to understand system latencies.
based on a regular 2 node mixed load perf test, 90th percentile woq latencies are really high, (1000 seconds)
please see the attached graphs.
graph # 1: sanity test,90th percentile latencies are around 45 sec.
graph # 2: mixed 2 node test, 90th percentile latencies are around 1000 sec...
From Steve Yen:
(g)woq means yet-another client thread is doing a workload of the following...
- Get an item
- Write (do a mutation on that item)
- Observe that it persists
- Query some view
And measure latency (Observe and Query time).
