Parallel scan/scroll


is there an option to perform scan&scroll in parallel. (client side)
sometimes it takes 6 seconds between scroll iterations

the problem i see, is that the scrollid may be changed.

in the server side: is it multithreaded? is there a setting to configure how many threads participating in it?


On the server side, there is one working thread per shard.

As you said, scroll ids can change so if you want to parallelize logic on client-side, you still need to make sure that the call to get the next page is not parallelized.
