Analysis: high concurrency, large data write data, will write the data into memory, accumulate a certain amount, and then in a timed or quantitative write to disk (reduce the disk IO (input/output)), eventually will load the data into memory and provide external access . Characteristics: Advantages: Write data to memory, high performance, fast speed (Weibo, SNS, Seconds Kill product) Cons: You may lose a piece of data in memory that has not yet been saved to disk ways to resolve data wit
