Backward Chaining

Rules when executing in multiple threads ..

Workshop - Backward Chaining

There are rules on the sequence in which Job Entries are executed.

In this workshop, the Job Entries were placed on the canvas in the following order:

• START

• Transformation A

• Transformation B

• Transformation C

• Success

START > Transformation A is executed first.

Even though Transformation C and Success were placed on the Canvas after Transformation B .. they will be executed before Transformation B as there's a hop from Transformation A.

Once the Transformation A pipeline has been completed with a success then Transformation B will be executed.
