Which method is recommended for mass updates in Guidewire?

Using paging with regular commits is the most efficient and safest method for mass updates in Guidewire. This approach involves breaking down the update process into smaller, manageable chunks (pages) instead of trying to update all records at once. By doing this, it helps manage system load and prevents potential performance degradation during the update process.

Regular commits after processing each page of data also ensure that the system maintains data integrity and reduces the risk of data loss in the event of an error. If an update fails, it limits the amount of data that may need to be rolled back, as only the records in the most recent page would need to be reprocessed.

Additionally, this method provides better resource management by allowing the system to operate efficiently without hogging all available resources, which could impact other users or processes. It creates a balance between achieving the required updates while also ensuring the system remains stable and responsive throughout the update procedure.
