Ok, I understand the theory/guideline/commandment is that reductions should really only be scalars and structures that grow can have all kinds of terrible effects on performance, cause cancer, etc., but I don't know how hard this rule is. Here is my use case:
I'm reducing mapped data of no more than around a dozen or so docs per reduction. The dozen docs are transactions and will contain transaction IDs that are not longer than a GUID. Can I get away with concatting a list of that size within my reduction without dooming us all? Thanks in advance for any guidance. -Will
