   > @Sladerix Really neat graphs - how'd you draw these?

   > It sounds like you want to "retain" some parameters across functions in the sequence. The best way to do this with openwhisk is to use composer and the `retain` combinator https://github.com/apache/openwhisk-composer/blob/master/docs/COMBINATORS.md.

   Thank very much !
   I think I need to deepen the openwhisk-composer topic. I don’t know how to use it because i learned by using only the CLI/API. But thanks for the example , i will take a look 😁
   
   
   About the graphs: 
   Those are only fast sketches to show a simple example for the issue, and I used GoodNotes5 for iPad.
   
   however to achieve a nicer form  I use draw.io (webapp and desktop version), very useful.
