require huge overhead and a performance cap, and it's never possible to use a single machine to support all of the load on Google and Facebook. In view of this situation, we need a new database because the relational database does not run well on the cluster. You might as well build a relational db cluster, but they're using shared storage, which is not the type we want. So there's a nosql era in which Google, Facebook, and Amazon are trying to handle more transmissions.NoSQL eraThere are a lot

At the same time, it is interesting that acid is acidic in English, base meaning is alkali) (basic available, soft state, eventually consistent) Understand the difference between persistence and non-persistence. That's because some nosql systems are purely memory-stored. You must be aware of the essential differences between traditional relational databases and nosql syste
has introduced a number of new types of databases to address several of the requirements mentioned above, and since they are designed to be quite different from traditional NoSQL databases, they are collectively referred to as "NoSQL" series databases. On the whole, in design, they are very concerned about the high concurrency of data read and write and storage of large amounts of data, compared with the relational database, they are in the architecture and data model side of the "subtraction",

different partitions. In this respect, the database provides several different consistency models: Atom writes. If the database provides an API, a write operation can only be a single atomic assignment, and the way to avoid writing conflicts is to find the "latest version" of each data. This allows all nodes to obtain the same version at the end of the update, regardless of the order in which the updates are made, and network failures and delays often result in inconsistent seque

Facebook, Amazon, and Twitter. They need to distribute data to many servers. Traditional relational databases do not meet this scalability requirement. They need a single database node to execute all the operations of the same transaction.Therefore, a batch of distributed, NoSQL key-value pairs were developed to meet the scalability requirements of these large-scale applications. Such data storage includes NoSQL databases such as MongoDB and Cassandra

According to the monthly ranking website db-engines.com data, Redis is the most popular key-value pair store database.Cassandra: Apache Cassandra (commonly referred to as c* in the community) is a set of open source distributed NoSQL database systems.Originally developed by Facebook to store simple format data such as Inbox, Google BigTable's data model integrates
database should be able to handle this conflict and ensure that multiple write requests are not processed by different partitions. This database provides several different consistency models: Atomic writing. If the database provides an API, a single write operation can only be a separate atomic assignment, the way to avoid writing conflicts is to find the "latest version" of each data. This allows all nodes to get the same version at the end of the update, regardless of the order of
