Struct AdmissionParameters 

Source 
pub struct AdmissionParameters {
    pub max_subscriptions_per_peer: u32,
    pub max_header_fetches_per_peer: u32,
    pub max_transaction_fetches_per_peer: u32,
    pub max_commit_fetches_per_peer: u32,
}
Expand description

Per-peer, per-RPC concurrency caps for the inbound consensus gRPC server.

Each cap bounds how many concurrent requests of one RPC group a single committee peer (keyed on its authenticated authority index) may have in flight; a peer cannot consume another peer’s budget. These are local, non-protocol parameters — heterogeneous values across authorities are safe, so they can be rolled out and tuned per node.

The defaults are sized for ~100-validator committees and the local synchronizer fan-out toward one server. 0 disables admission for that group.

Fields§

§max_subscriptions_per_peer: u32

Max concurrent block-subscription streams per peer.

If unspecified, this will default to 2.

§max_header_fetches_per_peer: u32

Max concurrent header fetches per peer (fetch_block_headers + fetch_latest_block_headers).

If unspecified, this will default to 32.

§max_transaction_fetches_per_peer: u32

Max concurrent transaction fetches per peer (fetch_transactions).

If unspecified, this will default to 16.

§max_commit_fetches_per_peer: u32

Max concurrent commit fetches per peer (fetch_commits + fetch_commits_and_transactions).

If unspecified, this will default to 8.
