What strategies can be used to read every row in a large Oracle table, only once, but as fast as possible with JDBC & Java ?

Consider that each row has non-trivial amounts of data (30 columns, including large text in some columns).

Some strategies I can think of are:

• Single thread and read table. (Too slow, but listed for clarity)
• Read the id's into ConcurrentLinkedQueue, use threads to consume queue and query by id in batches.
• Read id's into a JMS queue, use workers to consume queue and query by id in batches.

What other strategies could be used ?

For the purpose of this question assume processing of rows to be free.
