When do we exchange a registry of Jars? Is this stored in ZK? If so, do we
have to worry about the total size of the resulting ZK zNode? Have we done
performance checks to see what happens if the user has registered, say, 100
jars of 5 functions each? Should we consider a ZK structure (if that is what
this is for) of the form:
.../udfs
jar1: <JAR>
jar2: <JAR>
That is, store the list of jars as zNodes, where each zNode defines one jar?
