(looks good experimenting a bit on a server with 6000 tablets right now. I picked 8MB basically randomly, figuring that it's big enough for "good sequential IO" but small enough to get the benefit here. Initial experiments do show indeed a 6-8x improvement in startup time and disk usage. -- To view, visit http://gerrit.cloudera.org:8080/6911 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: Iadcda6b085e69cae5a15d54bb4c945d7605d5f98 Gerrit-PatchSet: 1 Gerrit-Project: kudu Gerrit-Branch: master Gerrit-Owner: Todd Lipcon <[email protected]> Gerrit-Reviewer: Adar Dembo <[email protected]> Gerrit-Reviewer: David Ribeiro Alves <[email protected]> Gerrit-Reviewer: Kudu Jenkins Gerrit-Reviewer: Mike Percy <[email protected]> Gerrit-Reviewer: Todd Lipcon <[email protected]> Gerrit-HasComments: Yes
