> Hive tables are case-insensitive. So any case specified in user queries are converted to lower case for query planning and all of the HMS metadata is also persisted as lower case names.
> However, with REMOTE data sources, certain data source will support case-sensitivity for tables.
> So HiveServer2 query planner needs to preserve user-provided case to be used with HMS APIs, for HMS to be able to fetch the metadata from a remote data source.
