Patch Set 1: (1 comment) https://asterix-gerrit.ics.uci.edu/#/c/2362/1//COMMIT_MSG Commit Message: PS1, Line 19: - Introduce max active writable datasets and use : it to automatically calculate the number of pages : of a user dataset memory component. > Hard to say. For me, I would rather configure storage.memorycomponent.numpa >From research point of view, I totally understand your point of view. However, >as a user, I should know the minimum datasets my application needs. The >description of this parameter can be made clear that miss setting it will >greatly impact the performance of ingestion. As you already mentioned, >currently, we allocate memory for the whole dataset, including all of its >partitions and indexes. When that problem is solve, the budget allocated using >the new parameter can be used to determine the rest. As for the dynamically >allocating a shared virtual buffer cache, we thought about it and we wanted to >solve the problem of running out of memory using it. However, since >implementing it will greatly change the current structure of memory >management, we decided to defer its implementation. -- To view, visit https://asterix-gerrit.ics.uci.edu/2362 To unsubscribe, visit https://asterix-gerrit.ics.uci.edu/settings Gerrit-MessageType: comment Gerrit-Change-Id: I9909c26b1e12b431f913e201d2c3d83769be7269 Gerrit-PatchSet: 1 Gerrit-Project: asterixdb Gerrit-Branch: master Gerrit-Owner: Murtadha Hubail <mhub...@apache.org> Gerrit-Reviewer: Anon.
