Retry time should be greater than cluster-node-time timeor the emphasis on fault tolerance, this is not for cluster, all application design is applicable. 3.2 Develop the Code of development Slow queries, process CPU 100%, client requests slow, or even time out. Avoid generating Hot-key, which causes the node to become the short board of

 NoSQL (NoSQL = not-only SQL), meaning "not just SQL"is a new revolutionary movement in the database, which was raised early on, and the trend is growing to 2009. NoSQL advocates are advocating the use of non-relational data storage, which is undoubtedly a new kind of thinking injection, relative to the overwhelming use of relational databases.

Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to a deluge of research and practice on protocols and algorithms.
