Matthias Boehm updated SYSTEMML-1435:
-------------------------------------
Summary: Extended transitive operator selection (was: Extended tansitive
operator selection)
> Extended transitive operator selection
> --------------------------------------
>
> Key: SYSTEMML-1435
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1435
> Project: SystemML
> Issue Type: Sub-task
> Components: Compiler
> Reporter: Matthias Boehm
> Fix For: SystemML 1.0
>
>
> This task aims to revisit and extend the current "transitive operator
> selection" decisions, which allow us to pull operations, which receive their
> inputs from other spark operations and likely reduce data sizes into spark
> execution type even though these operations would fit in memory.
> Examples with missing transitive operator selection are right indexing and
> grouped aggregates.
