RemoteProcessClient

laminar_db::process_function::remote

Struct RemoteProcessClient 

Source 
pub struct RemoteProcessClient { /* private fields */ }
Expand description

Bounded v1 gRPC/Arrow client. Clones share one connection pool and one invocation credit pool. Only explicit IP loopback endpoints are accepted by this development transport.

Implementations§

Source§

impl RemoteProcessClient

Source

pub fn descriptor(&self) -> &ProcessFunctionDescriptor

Immutable descriptor negotiated when this client connected.

Source

pub const fn max_in_flight(&self) -> usize

Number of invocation credits shared by clones of this client.

Source

pub async fn connect_loopback( endpoint: &str, descriptor: ProcessFunctionDescriptor, max_in_flight: usize, timeout: Duration, ) -> Result<Self, DbError>

Connect to a reference worker over an explicit loopback address.

§Errors

Rejects nonloopback/plaintext deployment, invalid bounds, or connection failure.

Source

pub async fn invoke( &self, scope: &RemoteInvocationScope, activations: &[ProcessActivation], ) -> Result<Vec<ProcessActivationResult>, DbError>

Invoke one key-distinct, single-vnode batch. A complete validated response is returned; the caller must still validate and apply it under its authoritative ownership fence.

§Errors

Rejects malformed inputs/responses, budget excess, timeout, or transport failure.
