The old algorithm is not using the ACK feature of
Cluster structureThe storm cluster surface resembles a Hadoop cluster. But on Hadoop you run "MapReduce Jobs" and you Run "topologies" on storm. "Jobs" and "topologies" are very different, a key difference is that a mapreduce job will eventually end, and a topology will always handle the message (or until you kill it).The storm cluster has two types of nodes: the

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 that the previous step calculates the output as
