Transaction-Based Traversal-Free Data Synchronization Among Multiple Sites

A product data management (PDM) data processing system comprising:

• a processor;
• and
• an accessible memory, the data processing system particularly configured to
• determine a plurality of persistent objects in a data structure to be replicated to a plurality of replication sites, wherein the plurality of persistent objects is identified based on a transaction table entry identifying a specific scoped transaction;
• determine specific persistent objects of the plurality of persistent objects to be replicated to each of the plurality of replication sites based on which of the plurality of persistent objects have been updated since last being replicated to each respective replication site, without traversing the full data structure;
• initiate a synchronization transaction according to the specific persistent objects;
• and
• replicate the specific persistent objects to at least one of the plurality of replication sites, without traversing the full data structure.

A non-transitory computer-readable storage medium encoded with computer-executable instructions that, when executed, cause a product data management (PDM) data processing system to:

• determine a plurality of persistent objects in a data structure to be replicated to a plurality of replication sites, wherein the plurality of persistent objects is identified based on a transaction table entry identifying a specific scoped transaction;
• determine specific persistent objects of the plurality of persistent objects to be replicated to each of the plurality of replication sites based on which of the plurality of persistent objects have been updated since last being replicated to each respective replication site, without traversing the full data structure;
• initiate a synchronization transaction according to the specific persistent objects;
• and
• replicate the specific persistent objects to at least one of the plurality of replication sites, without traversing the full data structure.
