             Summary: Document suggested settings for PressureAwareCompactionThroughputController
                 Key: HBASE-25632
                 URL: https://issues.apache.org/jira/browse/HBASE-25632
             Project: HBase
          Issue Type: Task
          Components: Compaction, documentation
    Affects Versions: 2.3.0
            Reporter: Nick Dimiduk


After upgrading a cluster to 2.3, we noticed that compactions were taking much longer. We tracked this down to the {{PressureAwareCompactionThroughputController}}, which became default as part of our upgrade. Our default configuration settings set the lower bound: 50MB/s, upper bound: 100MB/s. These settings make sense if you have a 1gbit NIC (~120 MB/s). For a 10gbit NIC, they’re quite inadequate.

Let's document this component explicitly and mention it as a call-out in the section on upgrading. Bonus points if we can provide suggested configuration values for the common networking configurations.
