Tim Armstrong resolved IMPALA-6519. ----------------------------------- Resolution: Fixed Fix Version/s: Impala 2.12.0 Impala 3.0 > Allow atomic allocation of an unreserved buffer > ----------------------------------------------- > > Key: IMPALA-6519 > URL: https://issues.apache.org/jira/browse/IMPALA-6519 > Project: IMPALA > Issue Type: Improvement > Components: Backend > Reporter: Tim Armstrong > Assignee: Tim Armstrong > Priority: Major > Labels: resource-management > Fix For: Impala 3.0, Impala 2.12.0 > > > [~kwho] needs this for his KRPC work. We want the exchange node to allocate > buffer pool buffers to store incoming data. However, the current interface > doesn't easily allow multiple threads to allocate buffers for which they > don't have reservations. Generally allocating buffers without having a > reservation would be an anti-pattern but it is a useful transitional > mechanism until we can reserve memory for the exchange node. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
