--------------------------------------
Summary: Rate limiting of major compactions
Key: ACCUMULO-4187
URL: https://issues.apache.org/jira/browse/ACCUMULO-4187
Project: Accumulo
Issue Type: Improvement
Components: core, tserver
Affects Versions: 1.8.0
Reporter: Shawn Walker
Priority: Minor
In discussing [ACCUMULO-4166] with Keith Turner, we decided that the underlying
issue is that major compactions can overwhelm a tablet server, rendering it
nearly unresponsive.
To address this, we should take a cue from Apache Cassandra and restrict how
quickly we perform major compactions. Rate limiting reads and writes involved
in major compactions will directly affect the IO load caused by major
compactions, and should also indirectly affect the CPU load.
