Todd Lipcon updated KUDU-1848: ------------------------------ Target Version/s: Backlog (was: 1.3.0) > Simplified dictionary-compression for in-memory data > ---------------------------------------------------- > > Key: KUDU-1848 > URL: https://issues.apache.org/jira/browse/KUDU-1848 > Project: Kudu > Issue Type: Bug > Components: perf, tablet > Affects Versions: Backlog > Reporter: Todd Lipcon > Assignee: Todd Lipcon > > In use cases that insert a lot of dictionary-codable data, we find that the > MRS fills up rather rapidly, partially due to many repeated copies of the > same values. It would be relatively simple to keep an in-memory dictionary of > the most recent N binary values, and on insertion, check if we have recently > inserted the same value. If so, we don't need to make a second copy of it in > the MRS arena. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
