Description

Initial DML implementation does not allow to UPDATE columns that correspond to key or its fields - direct modification would probably damage the index as well as hash map integrity, so UPDATE for such cases would need to do first remove, then put.
In the course of review, it has been agreed that this feature will be implemented in later releases shortly to deliver initial implementation on time.
