It is possible to execute multiple source-to-destination transformations (extract-load) in parallel threads.
By default, Etlworks integrator creates as many threads as there are parallel transformations. In some cases, it makes sense to limit the maximum number of threads, for example, to reduce the CPU utilization or to not exceed the API quote.
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.
