Tim Armstrong updated IMPALA-9810:
----------------------------------
Component/s: Backend
> Support Kudu's columnar scan format (Apache Arrow)
> --------------------------------------------------
>
> Key: IMPALA-9810
> URL: https://issues.apache.org/jira/browse/IMPALA-9810
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Reporter: Grant Henke
> Priority: Major
> Labels: kudu, performance
>
> Starting in Kudu 1.12 Kudu supports a columnar wire format that is Apache
> Arrow compatible. This format is significantly more efficient and faster than
> the row based format. Impala should support the columnar format, optimally
> operating on the arrow/columnar format natively.
> Of course using the columnar format natively is the best end result, but it
> might be beneficial enough to translate to the row based format client side.
> The Java client recently added a patch for this
> https://gerrit.cloudera.org/#/c/15983/ and Kudu could add similar C++ client
> functionality if needed.
