> Currently, we only compute and display hit ratio stats for the all time
> running period of the given region servers. For long running setups where
> most of the accessed data is cached, small recent periods of low hits would
> go undetected, since the larger number of long term hits would drive the hit
> average up.
> This proposes two additional properties:
> 1) "hbase.blockcache.stats.periods" which allows for defining a multiple
> window period;
> 2) "hbase.blockcache.stats.period.minute" which defines the length of each
> of these periods;
> If "hbase.blockcache.stats.periods" is defined and is greater than one, it
> creates a scheduled executor that rolls the metrics calculation at
> "hbase.blockcache.stats.period.minute" rate.
> BucketCache can then set a default window of 12 periods each 5 minutes long,
> providing metrics over the last hour, in addition to the all time hit ratio.
