This is the common entry point to insert different types of mutation operations in a record.

Parameters:

opType - The type of operation, such as set, set_or_replace, delete, and inc to be applied to the given field

rec - the record that is holding the mutation operation. Eventually this record will be serialized to encode the mutation in rowcol format

field - the path of the field on which the mutation is applied

value - the value for the mutation. For delete, it's the NULL type of the key value

Returns:

TRUE if the applied operation has an array that requires read, transform and write back on the server.
