> According to the new performance results presented in the HBASE-16417 we see
> that the read latency of the 90th percentile of the BASIC policy is too big
> due to the need to traverse through too many segments in the pipeline. In
> this JIRA we correct the bug in the merge sizing calculations and allow
> pipeline size threshold to be a configurable parameter.
