Most likely implementing antipatterns and/or poorly configured. Sub 1s is realistic but with some workloads still may require some tuning to maintain. Some workloads are very unfriendly to GCs though (ie heavy tombstones, very wide partitions).

When using Cassandra, how frequent or long have these pauses known to be? Even with tuning, is it safe to assume they cannot be eliminated? Would a 20-30 second pause be something out of the ordinary? Thanks.
