Ok, great! Since I am using the Java DSL, I will take the first approach.
Is there a way to pool this object so that there are many instances and
performance is not degraded under high-load circumstances? (I have seen
thread() instructions in the Java DSL, but I am not sure whether these would
be applicable in my scenario).
Thanks.
