Apache NiFi - Queues
Apache NiFi - Queues
The Apache NiFi data flow connection has a queuing system to handle the large amount of data inflow. These queues can handle very large amount of FlowFiles to let the processor process them serially.
The queue in the above image has 1 flowfile transferred through success relationship. A user can check the flowfile by selecting the List queue option in the drop down pst. In case of any overload or error, a user can also clear the queue by selecting the empty queue option and then the user can restart the flow to get those files again in the data flow.
The pst of flowfiles in a queue, consist of position, UUID, Filename, File size, Queue Duration, and Lineage Duration. A user can see all the attributes and content of a flowfile by cpcking the info icon present at the first column of the flowfile pst.
