To get some fine-grained control over a target setting, I will need to call it several times. Must I create a separate configuration in meltano.yml for each run? I thought about setting an environment variable before each execution, which I could reference as per https://meltano.com/docs/command-line-interface.html#pipeline-environment-variables. Any other approaches?

@adam_roderick I don't quite understand what you're trying to accomplish 🙂 Why do you need to call a target several times to set some target setting?

I'm using an s3 target that allows setting a key prefix. We have a data lake configuration that can use that prefix to create tables automatically in downstream database. But only if I can specify table names in the key. Running once per table and setting the key differently each time, was the only thing I had come up with at the moment.

Hmm, if it would help if Meltano did something clever with some new dynamic env vars based on the extractor's selected streams, let me know!
