Todd Lipcon resolved KUDU-1835. ------------------------------- Resolution: Fixed Fix Version/s: 1.3.0 > Support compression of the WAL > ------------------------------ > > Key: KUDU-1835 > URL: https://issues.apache.org/jira/browse/KUDU-1835 > Project: Kudu > Issue Type: Improvement > Components: log, perf > Reporter: Todd Lipcon > Assignee: Todd Lipcon > Fix For: 1.3.0 > > > In some workloads, particularly those which get good compression rates of the > underlying data (eg via dictionary coding), the WAL becomes a big bottleneck > for write performance. In addition, the large size of WALs can often mean > that old WALs get GCed rapidly and cause lagging replicas to get evicted > after only a temporary bout of slowness. Making WALs smaller would mean that > we can retain more history without the cost of disk space. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
