Fields

• txsSizeInflightPerPeer :: !SizeInBytes

  a limit of tx size in-flight from a single peer. It can be exceed by max tx size.

• txsSizePerBatch :: !SizeInBytes

  Hard limit on the total advertised transaction size in one body request batch, except for the first tx in a batch, which is requested even if it is larger. Hence a batch is at most `max txsSizePerBatch max_TX_SIZE`. The default reserves space for reply framing and for the const_MAX_TX_SIZE_DISCREPANCY tolerance of each tx. It MUST be positive, and the reply to the largest batch MUST fit within the StTxs size limit (see saneTxDecisionPolicy). It can be smaller than max_TX_SIZE: a larger tx is requested in a batch on its own.

• maxOutstandingTxBatchesPerPeer :: !Int

  a limit of outstanding tx-body request batches from a single peer.

• txInflightMultiplicity :: !Int

  from how many peers download the txid simultaneously

• bufferedTxsMinLifetime :: !DiffTime

  how long TXs that have been added to the mempool will be kept in the bufferedTxs cache.

• scoreRate :: !Double

  rate at which "rejected" TXs drain. Unit: TX/seconds.

• scoreMax :: !Double

  Maximum number of "rejections". Unit: seconds

• scoreAcceptDecrement :: !Double

  amount subtracted from the peer's score for each tx body the peer delivered that the mempool accepted.

• interTxSpace :: !DiffTime

  space between actual requests for the same TX. This the time a peer has soul ownership of their TX lease. When it expires other peers may issue additional requests.

• inflightTimeout :: !DiffTime

  Maximum time a peer's attempt may sit between claim and entering submission before the per-entry inflight-multiplicity cap is bumped, allowing another peer to attempt in parallel.

• maxPeerClaimDelay :: !DiffTime

  Maximum delay penalty for poor performing peers.

• disablePipelinedTxIdRequests :: !Bool

  When True, the txid picker never issues pipelined MsgRequestTxIds messages; only blocking requests fire (and only when the unack window has been fully drained). Used by some benchmarks.

Fields

• maxNumUnacknowledgedTxIds :: !NumTxIdsToAck

  maximum number of unacknowledged txids; it MUST be positive, and small enough for a MsgRequestTxs with that many txids to fit within the StIdle size limit (see max_TXID_SIZE). Before NodeToNodeV_16 it is a protocol parameter and must not be changed; since NodeToNodeV_16 it is a local setting.

• maxNumTxIdsToRequest :: !NumTxIdsToReq

  maximum number of txids an inbound client can request at a time.
