John Leach created HBASE-14540: ---------------------------------- Summary: Write Ahead Log Batching Optimization Key: HBASE-14540 URL: https://issues.apache.org/jira/browse/HBASE-14540 Project: HBase Issue Type: Improvement Reporter: John Leach
The new write ahead log mechanism seems to batch too few mutations when running inside the disruptor. As we scaled our load up (many threads with small writes), we saw the number of hdfs sync operations grow in concert with the number of writes. Generally, one would expect the size of the batches to grow but the number of actual sync operations to settle. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
