It is possible to execute multiple source-to-destination transformations (extract-load) in parallel threads.
By default, Etlworks integrator limits the number of threads to 5. To change the limit:
Step 1. Create a flow with parallel transformations.
Step 2. Create a nested flow and add a flow, created in step 1.
Step 3. Set the parameter Maximum Number of Parallel Threads to the positive integer > 1.
