------------------------------------
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.
