> Extend shared scan optimizer to reuse computation from other operators
> ----------------------------------------------------------------------
>
> Key: HIVE-16867
> URL: https://issues.apache.org/jira/browse/HIVE-16867
> Project: Hive
> Issue Type: Improvement
> Components: Physical Optimizer
> Affects Versions: 3.0.0
> Reporter: Jesus Camacho Rodriguez

> Attachments: HIVE-16867.01.patch, HIVE-16867.02.patch,

> Follow-up of the work in HIVE-16602.
> HIVE-16602 introduced an optimization that identifies scans on input tables
> that can be merged so the data is read only once.
> This extension to that rule allows to reuse 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.
> Follow-up extensions might remove this limitation.
