I'm trying to figure out if I can use an RDD to backend an interactive server. One of the requirements would be to have incremental updates to elements in the RDD, ie transforms that change/add/delete a single element in the RDD. It seems pretty drastic to do a full RDD filter to remove a single element, or do the union of the RDD with another one of size 1 to add an element. (Or is it?) Is there an efficient way to do this in Spark? Are there any example of this kind of usage?
Thank you, Kyle
