Two high-performance parallel computing engine storm and spark simple comparison

Spark is based on the idea that when the data is large, it is more efficient to pass the calculation process to the data than to pass the data to the computational process. Each node stores (or caches) its data set, and then the task is submitted to the node. So this is the process of passing the data. This is very similar to Hadoop map/reduce, in addition to actively using memory to avoid I/O operations, so that the iterative algorithm (the input tha
