How to group multiple processes into one

Hi everyone,

I'm trying to read multiple Mongo collections once (all the db) and exporting to MYSQL.

The problem is that I don't find the way to export all the db once. It only allows me exporting collections and it's to boring to do it manually (I have 35 collections in one db).

Can anyone help me please? I'm new at Knime and I may be asking something too simple.

Thank you


there is currently no way of listing collections from KNIME. But you should be able to list the collections in the MongoDB shell via "show collections" and then paste the list of collections into a table creator. From there you can use a chunk loop to go through the collections, transform them into a workflow variable with the Table Row to Variable node and use that variable in the MongoDB Reader to read the correct collection.
