I forget where I read it, but I was told that there is no de jure size limit on tuples. My topology will have tuples 1M in size, and outliers much larger than that. I haven’t seen any issues. Obviously at some point, you run out of memory…. ☺

Seems daunting to emit such a tuple. Any thoughts on that?

At a time I decide, I need to emit that map to the next bolt in the topology. I've tried it and it works, but I'm curious as to whether this is an anti-pattern or if there are problems with doing this that I am unaware of. Please and thanks, Marco.
