4. known system limitations
- Eventually consistent database (CAP Theorem - Performance over Consistency) - see Warning! AAI REST API Not Safe With Concurrent Access (i.e. more than 1 REST client)
- Basic issue is when running multiple instances and calls are made to the same objects concurrently, there runs the risk of creating duplicates or ghost vertices, see https://docs.janusgraph.org/advanced-topics/eventual-consistency/ for more
- We have provided a sticky config in HAProxy, to keep clients operating on the same instance for X mins and data grooming (via GraphAdmin) to clean up bad data
5. Used Models
AAI uses the following models:
- Inventory Model
6. System Deployment Architecture
See component section.
7. New Capabilities in this Release
