> Extend shared work optimizer to reuse computation beyond work boundaries
> ------------------------------------------------------------------------
>
> Key: HIVE-18361
> URL: https://issues.apache.org/jira/browse/HIVE-18361
> Project: Hive
> Issue Type: New Feature
> Components: Physical Optimizer
> Affects Versions: 3.0.0
> Reporter: Jesus Camacho Rodriguez
> Assignee: Jesus Camacho Rodriguez
> Labels: TODOC3.0
> Attachments: HIVE-18361.01.patch, HIVE-18361.02.patch,
> HIVE-18361.patch
>
>
> Follow-up of the work in HIVE-16867.
> HIVE-16867 introduced an optimization that identifies scans on input tables
> that can be merged and reuses the computation that is done in the work
> containing those scans. In particular, we traverse both parts of the plan
> upstream and reuse the operators if possible.
> Currently, the optimizer will not go beyond the output edge(s) of that work.
> This extension removes that limitation.
