h1. Design
The split function is supported, see
[https://spark.apache.org/docs/3.2.4/api/sql/index.html] , 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.
