Vectorized query execution for parquet tables

PraveenArch — Fri, 16 Sep 2022 09:54:38 GMT

Hi,

Looks like Apache Hive 0.14.0 supports vectorized query execution for parquet tables.

Is it supported in CDH 5.5.1 (Hive 1.1.0) ?

Project-history-wise, Apache Hive 0.14 eventually got renamed into Apache Hadoop 1.0. So yes, whatever is in Apache Hive 1.0.x is already in CDH 5.5.1 (which supplies Apache Hive 1.1.0 plus backports).

That said, I've not attempted to use the feature (if its not enabled by default).
