Shawn Walker commented on ACCUMULO-4187: ---------------------------------------- Created pull request https://github.com/apache/accumulo/pull/90 addressing this issue. > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
