> Rearrange DataType enumeration and Refactor type systems
> --------------------------------------------------------
>
> Key: TAJO-224
> URL: https://issues.apache.org/jira/browse/TAJO-224
> Project: Tajo
> Issue Type: Improvement
> Components: physical operator, planner/optimizer
> Reporter: Hyunsik Choi
> Assignee: Hyunsik Choi
> Fix For: 0.2-incubating
>
> Attachments: TAJO-224.patch
>
>
> This patch rebuilds DataType enumeration and refactors type systems for more
> efficiency and extendibility of type. In detail, it does as follows:
> * Remove the array return value from EvalNode, all functions, and Catalog.
> ** Now, all operators, functions, and expressions return only one data type.
> ** Instead, a data type can be array.
> * Add Type.PROTOBUF type that enables Tajo to use a protocol buffer class as
> a type.
> * Remove ArrayDatum and Type.Array which are used in some functions,
> requiring return two or more values.
> ** Instead, they use generated protobuf type as return types.
> * Add more rich data types to DataType.Type.
> * Add ProtobufDatum and ProtobufDatumFactory that help create Builder with
> only a data type.
> * Cleanup Catalog and many others.
