> Key: HIVE-9277
> URL: https://issues.apache.org/jira/browse/HIVE-9277
> Project: Hive
> Issue Type: New Feature
> Components: Physical Optimizer
> Reporter: Wei Zheng
> Assignee: Wei Zheng

> Attachments: HIVE-9277.01.patch, HIVE-9277.02.patch,

>
>
> We are proposing an enhanced hash join algorithm called “hybrid hybrid grace
> hash join”. We can benefit from this feature as illustrated below:
> o The query will not fail even if the estimated memory requirement is
> slightly wrong
> o Expensive garbage collection overhead can be avoided when hash table grows
> o Join execution using a Map join operator even though the small table
> doesn't fit in memory as spilling some data from the build and probe sides
> will still be cheaper than having to shuffle the large fact table
> The design was based on Hadoop’s parallel processing capability and
> significant amount of memory available.
