I have started playing with druid lately. I am still very novice here so please be with me if my question sound funny to you guys
As I understand, druid is useful for OLAP queries where use can slice, dice and visualize on different dimensions. Also druid uses hdfc or similar technology as deep storage. My question is can we use spark or other hadoop’s ecosystem friend like Mahout to read data directly and run ML or other iterative algorithms? Is there any Reader written for druid segments?
