Fields

• maxNumTxIdsToRequest :: !NumTxIdsToReq

  a maximal number of txids requested at once.

• maxUnacknowledgedTxIds :: !NumTxIdsToReq

  maximal number of unacknowledgedTxIds. Measured in NumTxIdsToReq since we enforce this policy by requesting not more txids than what this limit allows.

• txsSizeInflightPerPeer :: !SizeInBytes

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

• 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.
