Motivation

FLIP-123 has implemented HiveQL-compatible DDLs so that users can process metadata in HiveQL. This FLIP aims to provide syntax compatibility for queries. Similar as FLIP-123, this FLIP will improve interoperability with Hive and reduce migration efforts. Besides, this FLIP also makes it possible to extend HiveQL to support streaming features. And therefore, users may not only write HiveQL for batch jobs, they may also run streaming jobs in a HiveQL-fashion, which provides better batch-streaming unified experience for a migrating user.
