The Sequencer is designed to provide sequential processing of several workflows one after another in a certain order.

This feature can be used to automate complex ETL events, especially those for which the order of processing is crucial.

Overview

All streams are installed with the default EagleML package. No additional setup is required

The Sequencer involves the following streams:

eagle_ml-2-0_default_cm_sequencer – manages processing of an event (workflow); 
eagle_ml-2-0_default_cm_sequencer_sch – an autoexecuted stream based on eagle_ml-2-0_cm\schedule\sequencer.sch sch-rule – checks if there is a workflow in queue and triggers eagle_ml-2-0_default_cm_sequencer stream if the queue is not empty.

Additional stream: 

eagle_ml-2-0_default_cm_sequencer_cleanup – a support stream, which can be used to purge the queue of workflows or to remove a specific workflow from the queue.
