OverrideCatalog

trait OverrideCatalog extends Catalog

A trait that can be mixed in with other Catalogs allowing specific tables to be overridden with new logical plans. This can be used to bind query result to virtual tables, or replace tables with in-memory cached versions. Note that the set of overrides is stored in memory and thus lost when the JVM exits.
