The embodiments include the forming of object identification data in a leader node of query execution in the shared disk database cluster. At least one fragment of the query execution is distributed to at least one worker node in the shared disk database cluster, and the object identification data is utilized for multiversion concurrency control during query execution by the leader node and at least one worker node.
