Configuring load management options for data pages
Define the behavior of data pages in your Pega Platform application when the cache is no longer valid. For example, you can indicate that the data is no longer valid after a certain amount of time, or set Pega Platform to reload the page the first time a user interacts with it.
Use the following tasks to configure the load management options for a data page:
- Managing data page instances on the clipboard
To improve performance, you can remove all data page instances from the clipboard or only remove instances with specific parameter values.
- Configuring the refresh strategy for data pages
Define the parameters for refreshing the data page in Pega Platform. You can indicate that the data is no longer valid after a certain amount of time, or set your application to reload the page the first time a user interacts with it. The Refresh strategy section displays for read-only data pages.
- Defining data page access
To optimize data page performance and memory use, manage how the system responds when a requestor attempts to access a data page, or enable paging on the server for data pages that are sourced from a grid. The Page options section displays for read-only data pages with a scope of Requestor or Node, or savable data pages with a scope of Thread or Requestor.
- Allow API query for data pages
Improve performance for data pages that are used as the source of a table by designating the data page as queryable. The data page then loads only the necessary rows from the table. When you configure a queryable data page, you can filter columns, sort, and group data in a more performant way.
- Defining the access group for a node level data page
When a node-level data page loads, the system creates a new requestor to load the data page. Specify the access group of the requestor that determines the ruleset to use and the security context for rule resolution during the load. The Load authorization section displays for node-level data pages.
