Shashikant Banerjee updated HDFS-13227: --------------------------------------- Status: Patch Available (was: Open) > Add a method to calculate cumulative diff over multiple snapshots in > DirectoryDiffList > --------------------------------------------------------------------------------------- > > Key: HDFS-13227 > URL: https://issues.apache.org/jira/browse/HDFS-13227 > Project: Hadoop HDFS > Issue Type: Improvement > Components: snapshots > Reporter: Shashikant Banerjee > Assignee: Shashikant Banerjee > Priority: Major > Attachments: HDFS-13227.001.patch > > > This Jira proposes to add an API in DirectoryWithSnapshotFeature#f > DirectoryDiffList which will return minimal list of diffs needed to combine > to get the cumulative diff between two given snapshots. The same method will > be made use while constructing the childrenList for a directory. > DirectoryWithSnapshotFeature#getChildrenList and > DirectoryWithSnapshotFeature#computeDiffBetweenSnapshots will make use of the > same method to get the cumulative diff. When snapshotSkipList, with minimal > set of diffs to combine in order to get the cumulative diff, the overall > computation will be faster. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
