> 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.
