Perform a diff on the CUD of the table. There are 3 states,
`value1` is the old value and `value2` is the new value

* insert - value1 == empty, value2 != empty
* update - value1 != empty, value2 != empty
* delete - value1 != empty, value2 == empty

In addition, `column.size` x `count` == `value#.size`,
which can represent multiple records.

Strong type when generated, but type is lost after JSON serialization,
when JSON deserialized, value only has String and Number type
