Assignee: Divyesh Chandra
> When unconfigured, PressureAwareCompactionThroughputController should sniff
> NIC speed and use appropriate settings
> ------------------------------------------------------------------------------------------------------------------

> Key: HBASE-25633
> URL: https://issues.apache.org/jira/browse/HBASE-25633
> Project: HBase
> Issue Type: Improvement
> Components: Compaction
> Reporter: Nick Dimiduk
> Assignee: Divyesh Chandra
> Priority: Major
>
> 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.
> Suggestion: instead of using fixed values as the default for these
> configurations, we should sniff the NIC speed and configure for an optimal
> value according to available bandwidth.
