Resilience and Extensions​

  • Every distributed element has DB backed queues
  • HTTP/Remote connectors will retry until remote system available
  • Remote systems can be 'Busy'
  • There are no theoretical limits on the number of transactions that can be held in the queue. Limits come from disk space and software enforced limits.
  • Adding new outputs via Configuration - to Drives, Data Sinks, Service Endpoints and Queues
