i don't know about assembling the JSON fragments @thomas559 , but be aware the manifold.stream/stream->seq may cause blocking - if your app is non-blocking then you will probably want to use a combination of manifold.stream/map and manifold.stream/reduce instead

@mccraigmccraig - does it become blocking any time the stream is converted to a lazy seq, or is that specific to the stream->seq function? I was exploring either using lazy-seq to assemble the pieces, or else manifold.stream/transform.

@thomas559 it's because stream->seq does a deref internally, and deref is blocking - https://github.com/ztellman/manifold/blob/master/src/manifold/stream.clj#L552

using manifold.stream/transform should be fine

Ah, got it. Thanks!
