[jira] [Resolved] (IMPALA-5165) Allocate memory for all data from BufferPool

     [ https://issues.apache.org/jira/browse/IMPALA-5165?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tim Armstrong resolved IMPALA-5165.
-----------------------------------
    Resolution: Later

I think in the end this wasn't all that important - allocating small amounts of memory from MemPool is OK - it turned out that moving the large allocations to BufferPool was generally sufficient.
