Improved indexing performance by gradual retrieval of data
Valid from Pega Version 8.4
Search functionality in Pega Platform™ versions from 8.4.5 to 8.6 now includes the option to improve indexing performance when reading query results from a large table in a database. For example, to load the recommended 50 records at a time, in the Pega-SearchEngine ruleset, create the indexing/distributed/fetchsize dynamic system setting, and set the value to 50.
Creating the fetchsize dynamic system setting ensures that your system does not crash while indexing classes with numerous instances.
For more information, see Creating a dynamic system setting.
Tags disappear from Rich Text Editor source mode
Valid from Pega Version 8.5
When you use Rich Text Editor in HTML source mode, some tags disappear from the markup, which causes backward compatibility issues and data loss.
Cause
Pega Platform™ version 8.5.5 introduced the DOM Purifier security plugin. The plugin removes potentially vulnerable tags, including custom tags, from the raw HTML code in the Rich Text Editor source mode.
Workaround
You can disable the DOM Purifier plugin by adding the the window.disableDomPurifier = true markup to the userWorkForm HTML fragment rule.
Alternatively, as of Pega Platform version 8.5.6, you can add a tag to the allow list by including the window.rteCustomAllowedTags = ['myCustomTag'] snippet in the userWorkForm HTML fragment rule.
In Pega Platform versions 8.5.6 to 8.6, the iframe tag is added to the allow list by default.
