----------------------------------
Summary: Catalog should have a property to indicate
case-sensitivity
Key: SPARK-15147
URL: https://issues.apache.org/jira/browse/SPARK-15147
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.0.0
Reporter: Cheng Lian
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.
