Maximum Archival file size

General

Hi, we are in process to implement case archival using file system, we have around 12 million cases already in production out of which 8 million of cases would be eligible for case archival if we enable , we wanted to know if there is a limit on file size which would be created on per day /Month/year based on case resolution date per case type.

This depends on number of cases resolved on that particular day , but does pega has any max limit size which would be created.

Any inputs would be appreciated.

Based on Pega’s official documentation and support resources, there are no explicitly documented hard limits on the maximum file sizes that would be created when implementing case archival to a file system. Pega’s case archival architecture appears to be designed to handle large volumes of data without specific file size restrictions per day, month, or year based on case resolution date.

For your specific scenario with 12 million cases (8 million eligible for archival), here are some important considerations:

  1. Storage Infrastructure:
    • For Pega Cloud deployments, Pega Cloud File Storage (PCFS) is automatically used as the secondary storage repository
    • Pega Cloud production subscriptions include 500GB of file storage across all environments, with options to expand as needed (additional fees apply)
    • The system implements “soft limits” on storage space rather than hard restrictions
  2. Configuration Options:
    • Several dynamic system settings (DSS) allow you to control case archiving processing elements, such as max requestor limits
    • These settings can be adjusted for your specific application to improve performance when handling large volumes of cases
    • Pega configures default settings to support optimal performance based on their experience with clients
  3. Performance Considerations:
    • While there are no documented size limitations, the actual archival performance may vary based on:
      • The complexity of your case types
      • The amount of associated data being archived
      • Your available storage and processing resources
    • For very large volumes like yours, you might consider batching the archival process over time rather than attempting to archive all eligible cases at once
  4. Best Practices:
    • Implement a well-designed data retention policy to manage the lifecycle of archived cases
    • Thoroughly test the archival process with a smaller subset of cases before full implementation
    • Monitor system performance during archival operations and adjust batch sizes accordingly

Since you’re dealing with a substantial volume of cases (12 million total with 8 million eligible for archival), I would recommend reaching out to Pega Global Client Support for environment-specific guidance tailored to your implementation. They may be able to provide more specific recommendations based on your exact system configuration and case structure.
