> Improve QueryResultSet interface to allow appending a batch of rows at a time
> -----------------------------------------------------------------------------
>
> Key: IMPALA-7477
> URL: https://issues.apache.org/jira/browse/IMPALA-7477
> Project: IMPALA
> Issue Type: Sub-task
> Components: Backend
> Reporter: Tim Armstrong
> Assignee: Tim Armstrong
> Priority: Major
> Fix For: Impala 3.2.0
>
>
> The QueryResultSet interface used from PlanRootSink operates on a row at a
> time and is inefficient and inelegant. We can improve code readability by
> moving some logic from PlanRootSink to QueryResultSet and improve perf if we
> switch to an interface that allows appending a batch.
> This will make IMPALA-4268 incrementally easier.
> There are some TODOs in the code related to this.
