----------------------------------
Fix Version/s: 0.9.0
> Add latency metrics to the different KeyValueStore layers in Samza
> ------------------------------------------------------------------
>
> Key: SAMZA-467
> URL: https://issues.apache.org/jira/browse/SAMZA-467
> Project: Samza
> Issue Type: Improvement
> Components: container, kv
> Affects Versions: 0.9.0
> Reporter: Chinmay Soman
> Fix For: 0.9.0
>
>
> Currently we expose throughput related metrics in each of the key-value
> processing layers : (CachedStore, SerialzedStore, RocksDbKeyValueStore, ...).
> We should also add metrics like:
> * avg[Get/Put]LatencyMs
> * p95th[Get/Put]LatencyMs
> * p99th[Get/Put]LatencyMs
> These numbers are useful to correctly reason about the performance of a
> stateful stream processor. This will also help in debugging the case of a
> slowdown.
