Subject [jira] [Updated] (DRILL-1992) Add more stats for HashJoinBatch and HashAggBatch
Date Tue, 13 Jan 2015 17:49:35 GMT

     [ https://issues.apache.org/jira/browse/DRILL-1992?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Venki Korukanti updated DRILL-1992:
-----------------------------------
    Attachment: DRILL-1992-2.patch

Thanks Aman for reviewing. Changed "memoryAllocated" type to long in all places. Variable
length vectors template is missing the getCapacity() implementation (although its superclass
BaseDataValueVector has an implementation, it doesn't include offset vector capacity). For
fixed types, implementation is in superclass BaseDataValueVector.
