----------------------------------------
Summary: Extended tansitive operator selection
Key: SYSTEMML-1435
URL: https://issues.apache.org/jira/browse/SYSTEMML-1435
Project: SystemML
Issue Type: Sub-task
Reporter: Matthias Boehm
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.
