| System-SavedPages | Saves Thread contexts for a user after time-out. | |
| System-Updates-Cache | Identifies rules updated since the most recent system pulse, and so potentially stale in the rule cache of other nodes. | rule cache |
| System-User-MyRules | Controls favorites (and delegated rules), visible in the Favorite Explorer. | Favorites |
| System-Vtable-Cache-Entry | Entries in the VTable cache. | |
| System-Work-Indexer | Supports full-text search for work objects. Used by the Pega-RULES agent to hold agent queue entries after a new work item is created. After Elasticsearch indexing is complete, the agent queue entry is removed. | Working with the PegaRULES database — System tables |
