Subject Vectorized Query Execution in Hive
Date Mon, 08 Feb 2016 22:50:41 GMT
Hi,

 

Vectorized Query Execution
<https://cwiki.apache.org/confluence/display/Hive/Vectorized+Query+Execution
>  works on ORC files and is supposed to reduce the CPU usage and generally
improves the performance of jobs.

 

You can turn it on by using

 

set hive.vectorized.execution.enabled=true; 

 

Has anyone done any benchmark on this that are happy to share?

 

Thanks,

 

Mich Talebzadeh
