About Row-level Locking

About Row-level Locking

Informatica MDM Hub
uses row-level locking to manage data integrity when batch and
SIF
operations are executing concurrently on records in a base object. Row-level locking:
  • enables concurrent updates of base object data (the same base object but different records) from both batch and
    SIF
    processes
  • eliminates conflicts between online and batch processes
  • provides a high degree concurrent access to data, and
  • avoids duplication of the hardware necessary for a mirrored environment.
Row-level locking should be enabled if batch / API or API/API processes will be run asynchronously in your
Informatica MDM Hub
implementation. Row-level locking applies to asynchronous
SIF
and batch processing. Synchronous batch processing is restricted due to existing application-level locking.
