Subject Re: Enriching a tuple mapped from a datastream with data coming from a JDBC source
Date Mon, 12 Sep 2016 12:03:08 GMT
You can just use plain JDBC. Just keep in mind, that the classes will be
serialized and sent through the cluster. So probably, you want to
initialize all the non-serializable database access object in the open
method itself (as opposed to the constructor (client side)).
