Monster Scale Summit

Streaming, the process of scaling out/in to other nodes used to analyze every partition, one-by-one and was too slow and depended on the schema. File based stream is a new feature that optimizes tablet movement significantly. It streams the entire SSTable files without deserializing SSTable files into mutation fragments and re-serializing them back into SSTables on receiving nodes. As a result, less data is streamed over the network, and less CPU is consumed, especially for data models that contain small cells.
