Yes, Delta Sharing does support AWS PrivateLink. According to the official documentation, using AWS PrivateLink is a recommended way to enable private connectivity between clusters on the data plane and core services on the control plane within the Databricks workspace infrastructure.
To enable AWS PrivateLink for Delta Sharing, you can follow the steps outlined in the Databricks documentation:
Set up an Amazon VPC (Virtual Private Cloud) endpoint for Delta Sharing.
Configure the Amazon VPC security group and network access control list (ACL) to allow traffic to the Amazon VPC endpoint for Delta Sharing.
Create and setup a Delta Sharing server group. Assign a Security Group, and a List of private IPs (CIDR block) to it.
Share the Delta table you want to share externally using delta sharing.
Point clients to access the Delta Sharing server group endpoint URL using AWS PrivateLink.
