Aurora PostgreSQL Limitless Database maps to elastic clusters in Azure Database for PostgreSQL, which is managed Citus. Azure Cosmos DB for PostgreSQL, the older Citus service, is on a retirement path.
- Engine. Limitless is AWS-built sharding on Aurora's storage. Elastic clusters use the open-source Citus extension on flexible server nodes in a shared-nothing cluster.
- Sharding models. Elastic clusters support row-based and schema-based sharding. Limitless uses sharded and reference tables behind a router layer.
