There is a storm-jdbc component https://github.com/apache/storm/tree/master/external/storm-jdbc And it talks something about "lookup from database"
But its not really clear whether there is a JdbcSpout or not. A quick search through the code does not show JdbcSpout exists. If there were one, you could have used the Cassandra-JDBC driver.
