Transactional operations in multi-master distributed data management systems

A computer program product for grooming transactional operations in a multi-master distributed data management system, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• maintain, by the processor, transactional operations in at least one transaction-local side-log;
• perform, by the processor, a table log scan for a table including recording identification for each record in a log;
• and
• generate and write, by the processor, tuple sequence numbers for the records and the records on groomed transaction blocks to the table, respectively.

An apparatus comprising:

• a memory configured to store instructions;
• and
• a processor configured to execute the instructions to:
• maintain transactional operations in at least one transaction-local side-log;
• perform a table log scan for a table including recording identification for each record in a log;
• and
• generate tuple sequence numbers for the records and write the records on groomed transaction blocks to the table.
