I have a pairRDD and I would like to access a specific key-value.The first thing that comes to mind is filtering using the specified key, but that seems very inefficient as that would iterate over the entire RDD. And even more so if I need to access several keys.
Is there any other way to perform this ? this seems like a really useful feature. Im guessing that in order to implement this, I would need a mapping of keys to partitions, and a method to access data from a specific partition.
