--------------------------------------------
Summary: per-request profiling
Key: HBASE-6215
URL: https://issues.apache.org/jira/browse/HBASE-6215
Project: HBase
Issue Type: New Feature
Reporter: Kannan Muthukkaruppan
Assignee: Kannan Muthukkaruppan
Add ability to get HBase metrics back from an individual request. Apps can use
this to track fine-grained metrics (such as server-side latency, block cache
access/hit count; sync latency; append latency; etc.) on a per-API call basis.
Also, enhance HBase shell to also support this feature. [For example, if in the
shell we turn profiling on, for all subsequent requests the profiling stats
will be pretty printed, or optionally written to a file.]
