- participantResponseTimeout
the amount of time (w.r.t. the sequencer clock) that a participant may take to validate a command and send a response. Once the timeout has elapsed for a request, the mediator will discard all responses for that request. Choose a lower value to reduce the time to reject a command in case one of the involved participants has high load / operational problems. Choose a higher value to reduce the likelihood of commands being rejected due to timeouts.
- mediatorReactionTimeout
the maximum amount of time (w.r.t. the sequencer clock) that the mediator may take to validate the responses for a request and broadcast the result message. The mediator reaction timeout starts when the confirmation response timeout has elapsed. If the mediator does not send a result message within that timeout, participants must rollback the transaction underlying the request. Chooses a lower value to reduce the time to learn whether a command has been accepted. Choose a higher value to reduce the likelihood of commands being rejected due to timeouts.
- transferExclusivityTimeout
this timeout affects who can initiate a transfer-in. Before the timeout, only the submitter of the transfer-out can initiate the corresponding transfer-in. From the timeout onwards, every stakeholder of the contract can initiate a transfer-in, if it has not yet happened. Moreover, if this timeout is zero, no automatic transfer-ins will occur. Choose a low value, if you want to lower the time that contracts can be inactive due to ongoing transfers. Choosing a high value currently has no practical benefit, but will have benefits in a future version. TODO(M41): Document those benefits
- topologyChangeDelay
determines the offset applied to the topology transactions before they become active, in order to support parallel transaction processing
- ledgerTimeRecordTimeTolerance
the maximum absolute difference between the ledger time and the record time of a command. If the absolute difference would be larger for a command, then the command must be rejected.
- mediatorDeduplicationTimeout
the time for how long a request will be stored at the mediator for deduplication purposes. This must be at least twice the
ledgerTimeRecordTimeTolerance. It is fine to choose the minimal value, unless you plan to subsequently increaseledgerTimeRecordTimeTolerance.- reconciliationInterval
The size of the reconciliation interval (minimum duration between two ACS commitments). Note: default to StaticDomainParameters.defaultReconciliationInterval for backward compatibility. Should be significantly longer than the period of time it takes to compute the commitment and have it sequenced of the domain. Otherwise, ACS commitments will keep being exchanged continuously on an idle domain.
- maxRatePerParticipant
maximum number of messages sent per participant per second
- maxRequestSize
maximum size of messages (in bytes) that the domain can receive through the public API
- Exceptions thrown
DynamicDomainParameters$.InvalidDomainParametersifmediatorDeduplicationTimeoutis less than twice ofledgerTimeRecordTimeTolerance.

In some situations, the sequencer signs transaction with slightly outdated keys.

Be aware that if calling on a class that defines a LegacyProtoConverter, this method will still return a VersionedMessage. If the current protocol version maps to the legacy converter, deserialization will then fail (as it will try to deserialize to the raw protobuf instead of the VersionedMessage wrapper this was serialized to. Prefer using toByteString which handles this use case correctly.
