Restart Azure Cosmos DB for PostgreSQL

Important

Azure Cosmos DB for PostgreSQL is on a retirement path and no longer recommended for new projects. Instead, use one of these two services:

• For PostgreSQL workloads, use the Elastic Clusters feature of Azure Database For PostgreSQL to take advantage of horizontal scale-out and distributed PostgreSQL features within the open source Citus extension. For migration guidance, see migrate to Azure Database for PostgreSQL with Elastic Cluster.

• For NoSQL workloads, use Azure Cosmos DB for NoSQL for a distributed database solution that includes a 99.999% availability service level agreement (SLA), instant autoscale, and automatic failover across multiple regions.

You can restart your cluster for the Azure portal. Restarting the cluster applies to all nodes; you can't selectively restart individual nodes. The restart applies to all PostgreSQL server processes in the nodes. Any applications attempting to use the database will experience connectivity downtime while the restart happens.

1. In the Azure portal, navigate to the cluster's Overview page.

2. Select Restart on the top bar.

3. In the confirmation dialog, select Restart all to continue.

Next steps

• Changing some server parameters requires a restart. See the list of all server parameters configurable on Azure Cosmos DB for PostgreSQL.
