Struct AdmissionParameters 

Source 
pub struct AdmissionParameters {
    pub max_subscriptions_per_peer: u32,
    pub max_header_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.

0 (the default for every cap) disables admission for that group. At node start the protective preset fills the caps when all of them are left at 0; a caps block with any explicitly configured value is kept as-is, and CONSENSUS_GRPC_PROTECTIVE_LIMITS=0 disables the preset entirely. Preset values, sized for ~100-validator committees and the local synchronizer fan-out toward one server: subscriptions 2, header fetches 32, transaction fetches 16, commit fetches commit_sync_parallel_fetches (8).

Fields§

§max_subscriptions_per_peer: u32

Max concurrent block-subscription streams per peer.

§max_header_fetches_per_peer: u32

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

§max_transaction_fetches_per_peer: u32

Max concurrent transaction fetches per peer (fetch_transactions).

§max_commit_fetches_per_peer: u32

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