Josh Elser commented on PHOENIX-3807:
-------------------------------------
bq. Here's a patch which uses the HBase native metrics API. There's a check for
HBase version >= 1.4 for backwards compatibility, and a config flag.
Um, I'm starting to understand why this wasn't in patch-available :)
The new metrics API only shows up in HBase 1.4 (of which there is no such
release yet)

> Add server level metrics for secondary indexes
> - Histogram metrics for time to complete all secondary index updates per
> primary table update per index type. Will help us trend perf over time and
> catch impending issues.
> - Histogram metrics for number of updates dispatched to secondary index
> stores to service one primary table update per index type. Will help us catch
> inefficient behavior or problematic schema design.
> - Count of deployed secondary indexes by type. Will help understand and trend
> index usage, or catch deploy of an unwanted index type.
