Nicolas Spiegelberg commented on HBASE-5895:
--------------------------------------------
It should at least be optional to enable verbose logging. Another thought was
rate limiting the number of times a region could log a slow query over a given
time (to rate limit logging disk IO/sec)
> Slow query log in trunk is too verbose

> Key: HBASE-5895
> URL: https://issues.apache.org/jira/browse/HBASE-5895
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.96.0
> Reporter: Todd Lipcon
> Priority: Critical
>
> Running a YCSB workload against trunk, the slow query log ends up logging the
> entire contents of "mutate" RPCs (in PB-encoded binary). This then makes the
> logging back up, which makes more slow queries, which makes the whole thing
> spin out of control. We should only summarize the RPC, rather than printing
> the whole contents.
