In Storm Trident are batches processed sequentially? Or are they all processed in parallel? If they are processed in parallel how does it handle multiple writers to a datastore ?
I can understand this making sense for append-only implementations, but for cases where we are updating values in a database, how does it make sure that values are written, and in the database before another thread reads it and tries to update it with different data? Thanks -- Raphael Hsieh
