Struct Request 

pub struct Request {
    pub request_id: u64,
    pub tenant_id: u32,
    pub vshard_id: u16,
    pub plan: Plan,
    pub deadline: Instant,
    pub priority: Priority,
    pub trace_id: u64,
}

A request envelope sent from the Control Plane (Tokio) to the Data Plane (TPC).

This is a lightweight descriptor — bulk data lives behind Arc<[u8]> or slab handles, not inline in the ring buffer slot.

Fields

request_id: u64

Globally unique request identifier (monotonic per connection for 24h).

tenant_id: u32

Tenant scope for isolation and quota enforcement.

vshard_id: u16

Virtual shard this request targets.

plan: Plan

Opaque execution plan digest (interpreted by the Data Plane).

deadline: Instant

Absolute deadline — Data Plane must abandon work after this instant.

priority: Priority

Priority class for scheduling on the Data Plane core.

trace_id: u64

Distributed trace identifier for cross-plane observability.
