[jira] [Created] (HBASE-12986) Compaction pressure based client pushback

Andrew Purtell created HBASE-12986:
--------------------------------------

             Summary: Compaction pressure based client pushback
                 Key: HBASE-12986
                 URL: https://issues.apache.org/jira/browse/HBASE-12986
             Project: HBase
          Issue Type: Improvement
            Reporter: Andrew Purtell


HBASE-8329 recently introduced on all branches {{double RegionServerServices#getCompactionPressure()}}, which returns a value greater than or equal to 0.0, and any value greater than 1.0 means we have exceeded the store file limit on some stores. It could be reasonable to send this value along in server load statistics (clamping max at 1.0), and consider it as an additional term in the ExponentialClientBackoffPolicy.
