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.
