Michael Wall resolved ACCUMULO-4657. ------------------------------------ Resolution: Fixed Fix Version/s: 2.0.0 1.8.2 1.7.4 > BulkImport Performance Bottleneck > --------------------------------- > > Key: ACCUMULO-4657 > URL: https://issues.apache.org/jira/browse/ACCUMULO-4657 > Project: Accumulo > Issue Type: Improvement > Reporter: Matt Peterson > Assignee: Matt Peterson > Priority: Minor > Fix For: 1.7.4, 1.8.2, 2.0.0 > > Time Spent: 4h 50m > Remaining Estimate: 0h > > Outputting every "loaded" entry in the table is excessive, especially for > tables with multiple simultaneous bulk imports and multiple references to the > same file. This can cause performance problems. Even when the log level was > reduced, there was blocking within log4j. By doing that check once outside > the loop and only logging at trace level, bulk import performance improves > for such usages. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
