![]() Creating another database is currently not allowed, and the CREATE DATABASE command failsīy default this database is called citus. The Azure portal provides credentials to connect to exactly one database perĬluster. If Microsoft Entra ID is enabled on an Azure Cosmos DB for PostgreSQL cluster, the following is currently not supported: In Azure Cosmos DB for PostgreSQL clusters with burstableĬompute enabled, the following features are If you do need more vCores for a region in your subscription, see how to adjust compute quotas. The default quota should be more than enough to experiment with Azure Cosmos DB for PostgreSQL and run small to medium size production. ![]() Worker nodes, and vCores for burstable compute. Independently adjustable quotas: vCores for coordinator nodes, vCores for Compute Subscription vCore limitsĪzure enforces a vCore quota per subscription per region. See the available storage options and IOPS calculationįor various node and cluster sizes. Up to 2 TiB of storage is supported for single node configurations. Up to 32 TiB of storage is supported on coordinator and worker nodes in multi-node configuration. Storage on coordinator and worker nodes can be scaled up (increased) but can't Managed pgBouncer connection pooler configured for up to 2,000 simultaneousĬlient connections. You can scale connections further using connection Attempts toĬonnect beyond these limits fails with an error. The limits apply to both worker nodes and the coordinator node. The connection limits above are for user connections ( max_connections minus Maximum connections per node with burstable compute.It's important to limit simultaneous connections. Naming Cluster nameĪ cluster must have a name that is 40 characters orĮvery PostgreSQL connection (even idle ones) uses at least 10 MB of memory, so The following section describes capacity and functional limits in theĪzure Cosmos DB for PostgreSQL service.
