GitHub user dave-csc added a comment to the discussion: Dynamic creation of stream fields
Hi @gmitter-ef, I try to list some general strategies you could use (those I used in my projects, too). If you like to use only "standard" transform for processing data, but you don't know their schema in advance, the only way I found was including those transforms in an **ETL Metadata Injection**. When a transform requires a schema to be injected, you can either: - provide the static schema you like, using a **Data grid** for example - process a schema you have in previous transforms, in this case a **Metadata structure of stream** transform can help To get the output structure readable by Hop GUI, you need to set the output transform in the ETL Metadata Injection and provide the field structure you expect to be computed (note that this doesn't guarantee a successful execution for your project). As you can see, this is a very general explanation and cannot be more detailed... hope this helps anyway :) GitHub link: https://github.com/apache/hop/discussions/5005#discussioncomment-12460350 ---- This is an automatically sent email for [email protected].
