This has been a long dream of mine, since I added JSON support in #fs2-data. And it has never been so close to become true: the PR adding support for #JSON queries (think #jq) is ready! It allows for declarative streaming extraction and transformation of JSON data, emitting data as soon as some piece of output has been built, discarding input that has been consumed, on the go. I must admit, that I am super proud of this one! https://github.com/gnieh/fs2-data/pull/426
