Subject [Impala-ASF-CR] IMPALA-3201: in-memory buffer pool implementation
Date Wed, 28 Sep 2016 15:26:53 GMT
Hello Internal Jenkins, Dan Hecht,

I'd like you to reexamine a change.  Please visit

    http://gerrit.cloudera.org:8080/4070

to look at the new patch set (#10).

IMPALA-3201: in-memory buffer pool implementation

This patch implements basic in-memory buffer management, with
reservations managed by ReservationTrackers.

Locks are fine-grained so that the buffer pool can scale to many
concurrent queries.

Includes basic tests for buffer pool setup, allocation and reservations.
