These issues are not monitored by the product team responsible for our managed services. It might be easier to open a ticket in the portal for better visibility to the Product team.

For now I have asked product to have a look at this issue so you might get an answer here.

(thank you @thanodnl!)

@double-dubs thank you for the feedback! There're few things I see here:

• Worker nodes of different size
• Worker node removal
• Various cost saving capabilities

Worker node removal as a self-service option is something we would like to add to the product relatively soon. The priority for this capability is driven by how often our current customers need it in real life scenarios. So far removal needs are quite infrequent.

Enabling full lifecycle management of worker nodes of different size in clusters of different size is one of the advanced scenarios. It would more be in the 'cost saving' area. To better understand priority for this one we're monitoring patterns on the existing clusters as well as engaging with potential customers to discuss where their priorities are. At this point this capability looks like a rather long-term addition but sometimes things change fast.

We've added some cost saving capabilities to Azure Cosmos DB for PostgreSQL in the last couple of years starting with the most demanded ones. Ability to stop and start cluster compute (you don't pay for compute while it is stopped) and introduction of burstable compute for single nodes are examples of such capabilities.
All workloads have their own requirements but there're some patterns such as cyclic needs in increased cluster compute. So far such repeated cycles are quite long - daily or even weekly. We've seen some of the customers doing compute downscale (or stop) at the end of the day and upscale in the beginning of the day. All fully automated and routinely done on a daily basis.

We're certainly interesting in hearing opinions, so thank you very much once again for your feedback and sharing your thinking with us!
