----------------------------------------
Summary: Catalyst: Allow adding custom optimizers
Key: SPARK-9843
URL: https://issues.apache.org/jira/browse/SPARK-9843
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 1.4.1
Reporter: Robert Kruszewski
Currently there's only option to plug into query planning. This provides
limited capability for optimizing queries.
Allowing specifying custom optimizers would allow applications that make use of
spark sql tune their workflows. One example would be inserting repartitions
into query plan which isn't generally applicable but if you know range of
possible queries you can do that on the backend.
