  The FlowFiles enqueued in a Connection can also be deleted when necessary. The removal of the FlowFiles is initiated

  The following prioritizers are available:
  
  - *FirstInFirstOutPrioritizer*: Given two FlowFiles, the one that reached the connection first will be processed first.
  - *NewestFlowFileFirstPrioritizer*: Given two FlowFiles, the one that is newest in the dataflow will be processed first.
  - *OldestFlowFileFirstPrioritizer*: Given two FlowFiles, the one that is oldest in the dataflow will be processed first. This is the default scheme that is used if no prioritizers are selected.
  - *PriorityAttributePrioritizer*: Given two FlowFiles that both have a "priority" attribute, the one that has the highest priority value will be processed first. Note that an UpdateAttribute processor should be used to add the "priority" attribute to the FlowFiles before they reach a connection that has this prioritizer set. Values for the "priority" attribute may be alphanumeric, where "a" is a higher priority than "z", and "1" is a higher priority than "9", for example.
  
  *Note*: After a connection has been drawn between two components, the connection's configuration may be changed, and the connection may be moved to a new destination; however, the processors on either side of the connection must be stopped before a configuration or destination change may be made.
