--------------------------------------------
Summary: per-request tagging
Key: HBASE-6216
URL: https://issues.apache.org/jira/browse/HBASE-6216
Project: HBase
Issue Type: New Feature
Reporter: Kannan Muthukkaruppan
Assignee: Kannan Muthukkaruppan
Allow applications to tag individual RPC requests so that metrics exposed by
HBase can automatically be collected/aggregated by those tags. This'll be
useful for problem diagnosis across various applications-- as it will allow us
to correlate HBase metrics (such as data block misses) back to application
level tags.
For example, in some multi-tenancy type use case where many different
applications are served out of a single Table or CF, it'll be useful to know
the break down of metrics (such as bytes read, data block misses, get/put RPC
calls, etc.) by application name (tag).
