Dan Smith commented on GEODE-2651:
----------------------------------
Geode does support streaming results using ResultSender.addResult within the
function and using a custom result collector when executing a function.
However, geode does provide any sort of back pressure for this stream, so it's
possible that streaming back a large amount of data could still result in
running out of memory.
> Function service should provide built-in mechanism for streaming back large
> function results

> Project: Geode
> Issue Type: Improvement
> Components: functions
> Reporter: Jared Stewart
>
> It would be convenient to have a built-in mechanism for streaming back large
> function results that does not require keeping all results in memory on
> either end of the function execution. Example use cases:
> - Executing a function to gather all logs on server (this may produce a very
> large zip file)
> - Executing netstat -lsof currently runs out of memory in CI
