For a long time in the past, relational databases (relational database Management System) have been the most mainstream database solution, He uses things and relationships in the real world to explain the abstract data architecture in the database. However, in the explosive development of information technology today,

a write request from the partition's client. In this case, the request is forwarded from the cache to the main cache, the primary cache forwards the write request to the main cache of the primary partition, which is written to the master database, after the successful write, from the partition's main cache to notify the sub-region from the cache to update the cached value, the above operation is synchronous completion, Although the
