Stavros from TileDB, Inc. here: TileDB could be useful for storing your training data (in some storage backend of your choice) as well as your intermediate data (as davedx pointed out). But this would make sense only if your data are truly large and cannot fit in main memory. In fact, we are looking forward to seamlessly integrating with systems like TensorFlow, but we would rather wait until we can bring some value to applications with very large storage requirements.
