Tim Armstrong has posted comments on this change. Change subject: Headers and reservation logic for daemon-wide buffer pool ......................................................................
Patch Set 3: This is an initial commit building the buffer pool off to the side of the rest of Impala. I think it will be easiest reviewing the work in chunks: in a later commit we can switch over operators to using the pool. I started prototyping the switch for aggs and joins and was able to run some non-trivial queries. Compared to the previous patchset I posted, the reservation tracking is split out from the pool and the locking is much simpler. There are many other small changes and improvements. -- To view, visit http://gerrit.cloudera.org:8080/2569 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: I35cc89e863efb4cc506657bfdaaaf633a10bbab6 Gerrit-PatchSet: 3 Gerrit-Project: Impala Gerrit-Branch: cdh5-trunk Gerrit-Owner: Tim Armstrong <[email protected]> Gerrit-Reviewer: Dan Hecht <[email protected]> Gerrit-Reviewer: Marcel Kornacker <[email protected]> Gerrit-Reviewer: Michael Ho Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-HasComments: No
