             Summary: Pass DataType to source.Filter classes
                 Key: SPARK-7095
                 URL: https://issues.apache.org/jira/browse/SPARK-7095
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 1.3.0
            Reporter: Alex Liu
            Priority: Minor


source.Filter class doesn't pass any data type information.

e.g.
{code}
case class GreaterThan(attribute: String, value: Any) extends Filter
{code}

GreaterThan requires data are in the same type.

Data type matching check are required during Implementing PrunedFilteredScan where there are comparison filters.

Data type can be obtained by a case matching method. Since the method is called each time filter a row, it could improve performance if the data type is included in Filter.
