Question

How can I downgrade my DB cluster

Hi, I was able to upgrade my DB cluster, but there is no option to downgrade it! I don’t understand why not. I can downgrade and upgrade my droplets whenever I want, but not my DB cluster? Is there a way to do this, other than backing up, destroying and creating a smaller DB cluster.

If there isn’t another way, then please help me with my case, only 2 days in the entire month do I need the additional DB memory and CPU, and honestly I do not wish to spend the extra $60 or even $90 a month, just for those two high season days, so what can I do to avoid paying more than I should.

Do read only nodes help me with this case? Assuming I have reconfigured my software, to distribute connections between primary and read-only node, for read statements, does this help me with my case, when the high season is over, I could just destroy the read only node.

Or is there a better option, cause’ honestly this solution sounds like a lot of work.

Thanks

Hi @ALKateb,

At the moment Digitalocean does not support scaling down of a Managed database cluster from the UI, You can read about limitations here:

https://docs.digitalocean.com/products/databases/mysql/#limits

Alternatively, you can resize the database cluster to size your choice using DO API/DOCTL CLI.

DOCTL CLI:

https://docs.digitalocean.com/reference/doctl/reference/databases/resize/

doctl databases resize b1723184-32d7-41eb-8bb3-f911b6d9d449 --num-nodes 1 --size db-s-1vcpu-1gb

DO API:

https://developers.digitalocean.com/documentation/v2/#resize-a-database-cluster

Please note, there are 3 different slugs identifiers for machine type. You have to modify them according to your cluster resize slug size. For example

Basic Node :
{"size":"db-s-2vcpu-4gb", "num_nodes":1}

General Purpose Node :
{"size":"gd-4vcpu-16gb", "num_nodes":1}

Storage Optimized Node :
{"size":"so1_5-4vcpu-32gb", "num_nodes":1}

curl -X PUT -H "Content-Type: application/json" -H "Authorization: Bearer xxxxxx" -d '{"size":"gd-4vcpu-16gb", "num_nodes":1}' "https://api.digitalocean.com/v2/databases/{UUID}/resize"

I hope this helps!

Regards, Rajkishore
