A prerequisite of triggers are functions. Functions are a good chunk of work in themselves. I'd say we've built some more building blocks which might be useful but I don't think we're particularly close to starting to talk about implementing functions let alone triggers just yet. Out of curiosity, what are your use cases? I'd expect before triggers are implemented, we'll make changefeeds more powerful and robustly supported.
