corda.flow

Configuration schema for the flow section.

• event - Settings for external events within a flow.
  • maxRetries - The maximum number of times Corda retries a request before returning an exception.
    Default value: 5
    Minimum value: 0
    Maximum value: 2147483647
  • messageResendWindow - The length of time in milliseconds that Corda waits before resending unprocessed external events.
    Default value: 60000
    Minimum value: 1000
    Maximum value: 2147483647

• processing - Settings for flow pipeline processing.
  • cleanupTime - The length of time in milliseconds that the flow mapper holds onto its state for a flow that has finished. This value should be at least 2 times larger than the session.p2pTTL.
    Default value: 600000
    Minimum value: 1000
    Maximum value: 2147483647
  • maxFlowSleepDuration - The maximum delay in milliseconds before Corda schedules a periodic wake-up.
    Default value: 900000
    Minimum value: 1000
    Maximum value: 2147483647
  • maxRetryAttempts - The maximum number of times Corda retries a transient error before failing the flow. A value of zero disables retries.
    Default value: 5
    Minimum value: 0
    Maximum value: 1000
  • maxRetryDelay - The maximum delay in milliseconds before Corda schedules a retry.
    Default value: 16000
    Minimum value: 1000
    Maximum value: 2147483647
  • maxRetryWindowDuration - The duration in milliseconds after a transient error that Corda retries a flow before failing it. A value of zero disables retries.
    Default value: 300000
    Minimum value: 0
    Maximum value: 2147483647
  • poolSize - The size of the flow event processing pool size.
    Default value: 8
    Minimum value: 1
    Maximum value: 2147483647

• session - Settings for flow sessions.
  • cleanupTime - The length of time in milliseconds that the flow mapper holds onto its state for a session after the session has finished. This value should be at least 2 times larger than the session.p2pTTL
    Default value: 600000
    Minimum value: 10000
    Maximum value: 2147483647
  • heartbeatTimeout - The length of time in milliseconds that Corda waits when no message has been received from a counterparty before causing the session to error. This should be set at least 2 times larger than session.messageResendWindow.
    Default value: 1800000
    Minimum value: 1000
    Maximum value: 2147483647
  • messageResendWindow - The length of time in milliseconds that Corda waits before resending unacknowledged flow session messages.
    Default value: 120000
    Minimum value: 1000
    Maximum value: 2147483647
  • missingCounterpartyTimeout - The length of time in milliseconds to wait when the counterparty can't be found in a member lookup before causing the session to error
    Default value: 300000
    Minimum value: 1000
    Maximum value: 2147483647
  • p2pTTL - The TTL set in milliseconds. This is added to the current time and set on messages passed to the P2P layer to send to a counterparty. Messages received with a TTL timestamp set in the past will be discarded.
    Default value: 300000
    Minimum value: 10000
    Maximum value: 2147483647
  • timeout - The length of time in milliseconds that Corda waits when no message has been received from a counterparty before causing the session to error.
    Default value: 1800000
    Minimum value: 1000
    Maximum value: 2147483647
