Parallel Querying using Oracle

Perhaps a long awaited feature, this one is clearly the one that I like most.

Using pre-built packages its now possible to break a single (relatively heavy) operation into multiple small operations, which run in parallel. The benefits are obvious, and cant be ignored.

I am yet to ascertain the usability of such a feature with tools like informatica or pentaho, but I am quite sure a lot can be achieved, especially in the direction of updates to huge tables in data warehouses.

And looking at the implementation, its genuinely simple and straightforward.

Would be nice to see more applications utilizing the benefits of such features..
