> We are moving from Hive metastore catalog to a more general extensible catalog design. One problem that hasn't been taken care of in current Spark 2.0 interfaces is case sensitivity. More specifically, Hive metastore is case insensitive. It simply stores column names, table names, struct field names, and function names in lower case, and thus isn't even case-preserving. However, case sensitivity in Spark SQL is configurable. We need to add property (or properties) to {{Catalog}} interface to indicate case-sensitivity of underlying catalog implementations.
