Configuration of the statement protocol

Constants

DEFAULT_STATEMENTS_PER_SECOND

Default maximum statements per second before rate limiting kicks in.

INITIAL_SYNC_RESERVED_BYTES

Part of MAX_SEND_IN_FLIGHT_BYTES withheld from propagation while initial syncs are pending. Freed budget is otherwise reclaimed synchronously by parked propagations, while sync bursts only check on a timer and would always find the budget full.

MAX_PENDING_STATEMENTS

Maximum number of statement validation request we keep at any moment.

MAX_PROPAGATION_OUTBOX_LEN

Maximum number of statement hashes queued for propagation to one peer. On overflow the oldest hashes are dropped first.

MAX_SEND_IN_FLIGHT_BYTES

Soft limit on encoded statement chunks held in flight across all peers, shared by initial-sync and propagation sends. Since admission is checked before adding the next whole notification, it may be exceeded by less than one maximum-sized notification.

MAX_STATEMENTS_PER_NOTIFICATION

Most statements a sender can pack into a full MAX_STATEMENT_NOTIFICATION_SIZE notification. A batch declaring more is rejected before decoding.

MAX_STATEMENT_NOTIFICATION_SIZE

Maximum allowed size for a statement notification.

MIN_ENCODED_STATEMENT_SIZE

Minimum wire size of a valid statement: field-count prefix, AuthenticityProof and Expiry.

STATEMENTS_BURST_COEFFICIENT

Burst capacity coefficient for the rate limiter.
