Tracer file size limit to prevent disk usage issues
Valid from Pega Version 8.6
The maximum size of files with event details that Tracer generates is now 10 GB to avoid excessive disk usage and performance issues. Tracer applies the size limit at the node-level, so every node that runs in your system can use up to 10 GB of disk space to create an output file with event details. As a result, you can monitor the health of your system and deliver issue-free applications without experiencing disk space problems.

Deprecated support for Pega Platform deployments on embedded Cassandra
Valid from Pega Version 8.6
If you use Pega Platform™ decision management capabilities, Pega Platform uses Cassandra as the underlying storage system for the Decision Data Store (DDS), which manages the Cassandra cluster and stores decision management data in a Cassandra database. Future versions of Pega Platform will no longer support deployments on embedded Cassandra. In Pega Platform version 8.6, deployments using embedded Cassandra are deprecated but still work. To ensure future compatibility, do not create any new installations using embedded Cassandra.
For information about how to configure Pega Platform to access an external database, see Defining Pega Platform access to an external Cassandra database.
New dynamic setting to manage validation of hidden fields
Valid from Pega Version 8.6.4
Pega Platform™ version 8.6.4 introduces a new DSS setting for Theme Cosmos and other section-based applications. The validateHiddenField setting controls whether the application validates fields that you hide through visibility rules. By default, validateHiddenField is set to true
, which means that the application fields are validated for completeness even if they are not displayed in the form. You can also switch off this functionality by changing the setting value to false
.
For more information, see Managing field validation in hidden sections.
