What is the appropriate way to set the page size for mass updates?

Setting the page size for mass updates in Guidewire is crucial for managing data efficiently and ensuring optimal performance. The correct choice of setting the page size to 1000 aligns with best practices, as it strikes a balance between allowing a manageable number of records to process without overwhelming the system's resources.

In the context of mass data operations, if the page size is too small, it can lead to increased overhead from repeated requests to the database, which could hinder performance. Conversely, if the page size is excessively large, such as 5000, it could lead to timeouts and resource exhaustion as the system attempts to handle a substantial volume of data in a single transaction.

Setting the page size to 1000 helps ensure that the system can handle the updates effectively without sacrificing performance or leading to errors associated with processing large batches of data at once. It allows for a reasonable number of records to be processed while maintaining responsiveness and reliability during mass updates.
