Updated default dynamic system setting for requestor pools
Valid from Pega Version 8.4
Clients can now enable or disable requestor pools for processing service requests using a new dynamic system setting called EnableRequestorPools with Pega-IntegrationEngine as the owning rulest. Previously, all deployments utilized requestor pools to improve service processing response efficiency; requestor pools eliminated overhead by automatically returning a requestor to the pool after it fulfills a service request. Starting in Pega Platform 8.4, requestor pools are disabled in Client-managed cloud deployments, since these deployments use autoscaling to handle service request traffic. Enabling requestor pools in Kubernetes environments is not recommended, because they can inhibit the default autoscaling settings in the environment.
Requestor pools remain enabled by default in Pega Cloud and on-premises environments.
To help clients navigate this change, Pega has updated its best practice guidance for configuring requestor pools. For an overview, see Requestor pooling for services. For guidance on the use of requestor pools in your application, see the EnableRequestorPools entry in Dynamic system settings data instances.
Requestor pools are disabled by default in Pega Platform 8.4 in client-managed cloud deployments. Clients who deployed previous versions of Pega Platform on a Kubernetes environment and who upgrade to Pega Platform 8.4 could see that their services behave differently.
What steps are required to update the application to be compatible with this change?
If clients that are deployed in a Client-managed cloud environment need to configure their services to use requestor pools and they understand how to configure requestor pools for their optimized use, these clients can re-enable requestor pools. Clients should review the best practice for configuring requestor pools before they re-enable requestor pools. To re-enable requestor pools, you modify the EnableRequestorPools setting in the Pega-IntegrationEngine Owning ruleset from “disabled” to Enabled [no value]. For details, see Editing a dynamic system setting.
Valid from Pega Version 7.1.4
This release focused on improving the user experience of creating new rules and tightening up the use of specifications in the Case Designer. The layout of the New and Save As forms were made more intuitive and intelligent. Specification actions were made to be more consistent across various aspects of the Case Designer.
- After removing specification references, users can create and save a new specification.
- Developers may now choose either an existing specification or create a new one for subflows and Split-For-Each shapes.
- If a specification is not associated with flow shapes such as sub flows, Utilities, or Split-For-Each, it is possible to import speciications with the same names, and the flow shapes will default to using those imported specs.
- In the outline view, specification changes will be preserved when switching from tab to tab.
- The View Full Details functionality from either Configure Step or the Outline View will display all details, including the specification requirement links.
