> In some OLAP applications which has a separate query engine such as Tajo,
> they accept SQL-like languages and parse them to generate query plans.
> Mondrian is a representative example of these applications. If TajoClient
> accepts query plans of the JSON form, user queries can be efficiently
> executed without the duplicated parse phase.
