Riley Patterson updated HBASE-4117:
-----------------------------------
Labels: client ipc (was: )
Release Note:
Exposes JSON-parseable fingerprint and details for queries that take longer
than a configurable threshold time. The exposure is currently to the main
regionserver log, along with a (queryTooSlow) tag which allows it to be grepped
out and easily aggregated and/or monitored in adminstrator scripts.
The patch also provides a standard way to extract fingerprint and detail
information of interest by requiring each "DatabaseCommand" to provide a
fingerprint map and a details map, which will be a superset of the fingerprint.
Status: Patch Available (was: Open)

> Produce log messages for slow queries. The RPC server will decide what is
> slow based on a configurable "warn response time" parameter. Queries
> designated as slow will then output a "response too slow" message followed by
> a fingerprint of the query, and a summary limited in size by another
> configurable parameter (to limit log spamming).
