What are your (Amplitude’s) public IPs for connecting to external data warehouses as described in this doc: https://www.docs.developers.amplitude.com/data/destinations/redshift/#cloud-storage. I cannot find documentation giving either a list of IPs or a CIDR block to whitelist for cluster operators.
If the requirement is all public IPs (which frankly is absurd), then do you allow using an SSH bastion host and tunneling traffic? If so, where can I upload a public key to allow this connectivity to proceed?
I know that this is beta functionality, but I am looking to leverage it for a task internally to avoid having to use S3 as an intermediary layer and doing scheduled COPY operations.
