4.12 Using Automatic Delta Refresh to Handle Database Changes

You can automatically refresh (auto-refresh) graphs periodically to keep the in-memory graph synchronized with changes to the property graph stored in the property graph tables in Oracle Database (VT$ and GE$ tables).

Note that the auto-refresh feature is not supported when loading a graph into PGX in memory directly from relational tables.

• Configuring the Graph Server (PGX) for Auto-Refresh
  
• Configuring Basic Auto-Refresh
  
• Reading the Graph Using the Graph Server (PGX) or a Java Application
  
• Checking Out a Specific Snapshot of the Graph
  
• Advanced Auto-Refresh Configuration
  
• Special Considerations When Using Auto-Refresh
