Mysql consistent reading and mysql consistencyConsistent Nonlocking Reads Consistent read means that InnoDB uses multiple versions to provide a snapshot for querying a database at a certain time point. This kind of query shows the changes in transaction commit before the current world point, but not the changes committed since then, and not the uncommitted changes. An exception to this rule is that it can

Introduction to consistent hash algorithm The consistent hash algorithm is a distributed hash implementation algorithm proposed by MIT in 1997, and the goal of the design is to solve the hot issues in the Internet. The consistent hash algorithm proposes four definitions for determining the hash algorithm in a dynamically changing cache environment. balance (Balan

the nodes added later more active. Obviously, the hash algorithm above cannot do the same. Is there any way to change this situation? this is consistent hashing... 2 hashAlgorithm and monotonicity A metric of the Hash algorithm is Monotonicity, which is defined as follows: Monotonicity means that if some content is already allocated to the corresponding buffer through hash, new Buffering is added to the system. The hash result should ensure that the

A distributed hash (DHT) implementation algorithm, proposed by MIT in 1997, was designed to address hot spot problems in the Internet, with a similar intent to carp. The consistent hash corrects the problem caused by the simple hashing algorithm used by carp, so that distributed hashing (DHT) can be really applied in the peer-to-peer environment.The consistency hash algorithm proposes four definitions for determining the good or bad hash algorithm in

Since Redis is a single point, but it is unavoidable to use multiple Redis cache servers in the project, how do you map the cached key evenly to multiple Redis servers, and minimize the cache key hit rate as the cache server increases or decreases? This requires us to implement our own distribution.Memcached should be no stranger to everyone, by mapping the key to the memcached server for fast reading. We can dynamically increase its nodes without affecting the relationship between the key previ

The consistent hash corrects the problem caused by the simple hashing algorithm used by carp, so that distributed hashing (DHT) can be really applied in the peer-to-peer envi

The consistency hash algorithm has two key problems to be solved, one is the choice of data structure for node storage and lookup, and the other is the choice of node hash algorithm. First, let's talk about the data structure used to store nodes in the consistency hash algorithm. By understanding the principle of a consistent hash, we know that nodes can be imagined as being stored on a circular data structure (pictured below), where nodes A, B, C, a

Based on the analysis of the user model, Huawei released a new generation of Unified Communication solution oriented to user experience. A Unified Communication Interface unrelated to the specific terminal form and a practical and easy-to-use application business on the same communication interface are the soul of this solution. Technological innovation is no longer a fresh business. User Experience innovation is bound to become a trend of competition among major communication vendors.

When memcacheset is used to store data, it is necessary to calculate which memcache is to be placed based on the consistent hash algorithm. the implementation of this algorithm requires manual writing or installation, many memcache parameters are automatically configured. we only need to set them directly? When the memcache set stores data, it is necessary to calculate which memcache should be placed based on the
