wrap response builds whole string #58

Closed pete23 closed 5 years ago

pete23 commented 5 years ago

I have a usecase where I’m returning a large amount of data from a resultset, lazily. Using wrap response attempts to build the whole string on heap.

I have a hacked fork which uses generate-stream and an InputStream response to be more parsimonious about resources.

Is this something you’d be interested in a PR for? If so I may clean what I have up and fix tests etc.

That sounds fine, as long as it happens transparently. I assume you're just checking for a lazy seq?

pete23 commented 5 years ago

I haven’t bothered even doing that tbh, I just always stream. I guess there’s overhead to setting up the writer/stream machinery that we might want to avoid for the general case? If so the laziness of the seq might be a reasonable guess for whether we want streaming maybe? Hmmm. I’ll clean up and submit a first cut and maybe it’ll be more obvious to me then.

PR in the hopper. Let me know if you need any further work on it.

Hi, any plans to cut a release? I’m quite keen to throw my hacked versions away! :-)
