Bernhard Amann commented on BIT-1162:
-------------------------------------

It looks like BIT-1170 might completely (or at least nearly completely) solve this issue. However, we probably still should look for a way to make data aggregation quicker in this cases - it can take quite a while until all nodes have reported back...

> If you use sumstats on a Bro cluster and have one (or more) overloaded nodes, sumstats is near unusable at the moment.
> Sumstats asks for all keys in order. The speed of getting them seems to depend on the speed in which the individual cluster worker nodes answer.
> If there is a very slow node in the network, for sumstats with a higher number of keys, processing will just stop after just a few keys. No warning message or similar is output.
