> Semijoin: Implement a Long -> Hash64 vector fast-path
> -----------------------------------------------------

> Key: HIVE-18866
> URL: https://issues.apache.org/jira/browse/HIVE-18866
> Project: Hive
> Issue Type: Improvement
> Components: Vectorization
> Reporter: Gopal V
> Assignee: Sergey Shelukhin
> Priority: Major
> Labels: performance
> Attachments: 0001-hash64-WIP.patch, HIVE-18866.01.patch,
> HIVE-18866.patch, perf-hash64-long.png
>
>
> A significant amount of CPU is wasted with JMM restrictions on byte[] arrays.
> To transform from one Long -> another Long, this goes into a byte[] array,
> which shows up as a hotspot.
