uh, doing analytics type queries on large datasets that postgres would choke on, as an RPC? I'm using it (ducklake specifically) to build a lakehouse RPC server that can scale horizontally based on resource utilization in k8s.
Ducklake handles the metadata and storage, but a local duckdb instance connected to it still has to do the compute itself. This lets you federate access to the compute.
Fun for me, I just finished a big streaming implementation doing essentially the same thing in Go-gRPC with arrow table record batches. It was fun though.
