> The goal of this task is to move the Table API on top of Calcite and preserve the feature set of the batch part. Calcite is a SQL optimization and translation framework. It includes a SQL Parser, a catalog component, a validator, and a rule-based (relational) optimizer. This is the first step for adding SQL and StreamSQL support to Flink.
> Since the streaming part of the Table API is rather a proof-of-concept implementation and only features selection and projection, we exclude it from this task. With the current Table API, queries can only be embedded into DataSet (or DataStream) programs with manually defined schema for DataSet/DataStreams. We do not add support for external data stores (CSV, Parquet, ORC files, HBase, etc.) as part of this task. Instead we only consume data that comes from a DataSet/DataStream operator.
> More details can be found in the design document for SQL / StreamSQL on Flink.
