DataSkippingFileIndexRule

class DataSkippingFileIndexRule extends Rule[LogicalPlan]

A Catalyst rule which replaces a logical relation plan's InMemoryFileIndex with an extended DataSkippingFileIndex which allows fine grained file filtering.

The following applies to the case where plan is an instance of LogicalRelation, with a HadoopFsRelation: the rule adds a dummy option to the options field of the new HadoopFsRelation. if the input plan's catalog is not an instance of IndexedCatalog - then the dummy option will be absent, thus it's addition will ensure that org.apache.spark.sql.catalyst.trees.TreeNode.fastEquals will return false when comparing the input plan to the returned plan.

if the input plan's catalog is indeed an instance of IndexedCatalog - then the plan doesn't change, and indeed org.apache.spark.sql.catalyst.trees.TreeNode.fastEquals will return true - preventing an unnecessary catalyst churn.
