--------------------------------------
Summary: Eliminate duplicate filters from pushdown predicates
Key: SPARK-6715
URL: https://issues.apache.org/jira/browse/SPARK-6715
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Liang-Chi Hsieh
Priority: Minor
Now in {{DataSourceStrategy}}, the pushdown predicates are duplicate of
original {{Filter}} conditions. Thus, some predicates are performed both by
data source relation and {{Filter}} plan. I think it is a duplicate loading.
Once the predicates are pushed down and performed by a data source relation, it
can be eliminated from outside {{Filter}} plan's condition.
