Fully correct Steve, it is a source of confusion an having a standard pool at app/driver level will work as good as the jee solution, but just like the cql foresees an easy developer entry for cassandra because it is similar to sql, the jee datasource could do the same in front of the middleware audience. When I currently would like to convince my customers to give cassandra a try, then Im sure that several tech decission makers will say that the lack of a standard jee datasource impl is strange and will raise some concerns and influence the first perception and landing of the product. This while in one way it makes sence that there is no standard jee datasource solution present.
Seems to be indeed a topic for the java driver.
