[jira] [Commented] (SPARK-16717) Dataframe (jdbc) is missing a way to link and external function to get a connection

Hi, [~rjtokenring].
It seems not about Spark 1.3.0. Do you mean 1.3.0 really?

> In JdbcRRD it was possible to use a function to get a JDBC connection. This allow an external handling of the connections while now this is no more possible with dataframes. 
> Please consider an addition to Dataframes for using an externally provided connectionFactory (such as a connection pool) in order to make data loading more efficient, avoiding connection close/recreation.
