This document applies only to Astro Hybrid. To see whether you’re an Astro Hybrid user, click Organization Settings. Your Astro product type is listed under Product Type on the General page.To create a cluster on Astro Hosted, see Create a dedicated cluster.
Unless otherwise specified, new Clusters on Google Cloud Platform (GCP) are created with a set of default resources that our team has deemed appropriate for most use cases. Read the following document for a reference of our default resources as well as supported cluster configurations.

Supported Cloud SQL instance types

The following Cloud SQL instance types are supported on Astro:
  • Small General Purpose (2 CPU, 8 GiB MEM)
  • Medium General Purpose (4 CPU, 16 GiB MEM)
  • Large General Purpose (8 CPU, 32 GiB MEM)
  • Small Memory Optimized (2 CPU, 12 GiB MEM)
  • Medium Memory Optimized (4 CPU, 24 GiB MEM)
  • Large Memory Optimized (8 CPU, 36 GiB MEM)
  • Small Compute Optimized (4 CPU, 8 GiB MEM)
  • Medium Compute Optimized (8 CPU, 16 GiB MEM)
  • Large Compute Optimized (16 CPU, 32 GiB MEM)
  • XLarge Compute Optimized (24 CPU, 48 GiB MEM)
  • XXLarge Compute Optimized (32 CPU, 64 GiB MEM)
For detailed information about each instance type, see the Cloud SQL documentation. If you’re interested in an Cloud SQL instance type that is not on this list, contact Astronomer support.

​
Supported worker node pool instance types

Each worker node in a pool runs a single worker Pod. A worker Pod’s actual available size is equivalent to the total capacity of the instance type minus Astro’s system overhead. The following table lists all available instance types for worker node pools, as well as the Pod size that is supported for each instance type. As the system requirements of Astro change, these values can increase or decrease. If your Organization is interested in using an instance type that supports a larger worker size, contact Astronomer support. For more information about configuring worker size on Astro, see Deployment settings.
