Return stream or iterator from query

[pablote]

Is there any kind of support for returning a stream/iterator or similar? I'm not sure what the most idiomatic thing would be for Erlang. The use case would be for when you need to return very large datasets from the DB, and being able to start processing it without loading everything on memory.

As an example, this is available in node.js for this purpose: https://www.npmjs.com/package/pg-query-stream

Thanks

There isn't yet. Would have to manually do it. I was going to do notify/listen first which also will require pid tracking/sending.

Thanks for the quick reply. Good to know that, don't wanna dictate priorities but I'd imagine adding some sort or stream support would be simpler than a new feature as listen/notify. As is mostly the same kind of querying only that instead of accumulating data and then returning everything, results would be sent to the app immediately through some sort of iterator mechanism.
