[jira] [Created] (IMPALA-7477) Improve QueryResultSet interface to
allow appending a batch of rows at a time
Tim Armstrong created IMPALA-7477:
-------------------------------------
Summary: 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
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.
