Can we scale down AlloyDB machine type - vCPU and Memory once the cluster got created?

Hi @RavikumarV ,

Unfortunately, , directly scaling down the virtual CPUs (vCPUs) and memory (i.e., the machine type) of an existing AlloyDB cluster in Google Cloud is not supported.

  • AlloyDB is designed for high performance and availability. Reducing the machine type dynamically would require significant internal reconfiguration, potentially disrupting ongoing operations and cluster stability.

Possible Workarounds

Create a New Cluster

  • Procedure: Start by creating a new AlloyDB cluster with the desired, smaller machine type. Then, migrate your data from the existing cluster to the new one using data migration tools like pg_dump and pg_restore.

  • Considerations: This method will likely involve some downtime during the data migration process, and you'll need to handle the transfer of database connections and configurations.
