             Summary: MVCC TX: Two rows with the same key in one MERGE statement produce an
exception
                 Key: IGNITE-9265
                 URL: https://issues.apache.org/jira/browse/IGNITE-9265
             Project: Ignite
          Issue Type: Bug
            Reporter: Igor Seliverstov


In case the operation like {{MERGE INTO INTEGER (_key, _val) KEY(_key) VALUES (1,1),(1,2)}}
is called an exception is occurred.

Correct behavior: each next update on the same key overwrites pervious one
