Is Headless Service exposure of gRPC port necessary for Qdrant?

Question: Is Headless Service exposure of gRPC port necessary for Qdrant?

Hi Qdrant team,

I’m deploying Qdrant using the official Helm chart, and I’ve noticed that the gRPC port (default: 6334) is exposed not only via a LoadBalancer service but also via a Headless Service.

Since intra-cluster communication (e.g. Raft replication) uses the P2P port, and client communication typically goes through the LoadBalancer, I’m wondering:

• Is there any specific reason why the gRPC port is exposed via the Headless Service?
• Is it required for any internal use cases (like health probes, node-to-node gRPC calls, etc.)?
• If not mandatory, would it be safe to disable gRPC exposure in the Headless Service?

Thanks in advance! Really appreciate your work on Qdrant.
