Adar Dembo has abandoned this change. Change subject: log block manager: use extent maps to decide whether to truncate containers ......................................................................
Abandoned Todd and I discussed this offline. Given the impact of FS_IOC_FIEMAP, I ended up implementing the space heuristic he described and combining "unpunched holes" and "preallocated space beyond the end of the file" into one heuristic. I'm not using extent maps at all, though I'm leaving the door open to use them as a more precise way to handle unpunched holes. -- To view, visit http://gerrit.cloudera.org:8080/6585 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: abandon Gerrit-Change-Id: I3541f70721328d5af911f4889f8b4bcf0de3ebf8 Gerrit-PatchSet: 7 Gerrit-Project: kudu Gerrit-Branch: master Gerrit-Owner: Adar Dembo <a...@cloudera.com> Gerrit-Reviewer: Adar Dembo <a...@cloudera.com> Gerrit-Reviewer: David Ribeiro Alves <davidral...@gmail.com> Gerrit-Reviewer: Kudu Jenkins Gerrit-Reviewer: Todd Lipcon <t...@apache.org>
