-------------------------------------
h1. Design
The split function is supported, see Spark SQL, Built-in Functions, for the
two-parameter and three-parameter cases.
It is mainly for type and data conversion processing.
* The array<string> obtained from the downward-pressing query supports type
and data conversion.
* min/max metadata query for array<string> data conversion.
* Conversion of array<string> by hit aggregate index / detail index.
* Handling the above cases naturally supports computable column definitions.
