Hello,

at the moment we are using Talend for our ETL, but I like CloverETL more.

Is it possible to run subgraphs with parameters coming from rows.

MainGraph -> Reading dates
Iterate dates -> Running 1 graph per date

This brings us much more performance because we are using partitions etc.
Is that possible with CloverETL

Thanks in advance

  Hello MP3HiFi,
  subgraphs are not available in CloverETL, but for repeated execution of the same graph with different parameters you can use RunGraph component. For an example of the component usage see zip:cloverETL.examples.rel-3-0-0.zip/cloverETL/examples/SimpleExamples/graph/graphRunGraph.grf (download from http://sourceforge.net/projects/clovere ... p/download)

  Hi,
  
  that will do the trick, but unfortunenately RunGraph is not part of the CommunityEdition. So I will have to stay with Talend.
  
  Thanks

  Hello,
  it's not in Community Edition, but it is in open-source Engine. If you are able to write the graph without GUI, you can run it from command line.
