Memcached Memcached traditionally does not belong to the NoSQL category, but is a Distributed Key/Value memory cache solution that can be used to store a variety of temporary datasets, the storage method is no different from other NoSQL database solutions. NorthScale provides a Memcached package for 32-bit and 64-bi

Why is there NoSQL? With the development of the Internet, when we turn a server into two servers, when we start to build data backup, when we need to add a buffer layer, to adjust all the query, put more hardware.Finally, it is necessary to divide the data into multiple clusters and reconstruct a large number of application logic to fit the segmentation. After a while, you'll find yourself constrained by the data structure you've been designing a few

The difference between NoSQL and NoSQL is much greater than the difference between different SQL databases. Therefore, software architects must select a suitable NoSQL from the very beginning of the project. The difference between NoSQL and NoSQL is much greater than that be

Abstract: Although SQL database is a very useful tool, after 15 years of outstanding performance, the monopoly will be broken. This is only a matter of time: I was forced to use relational databases, but I finally found that I could not meet my needs. For details, see my IT-Homer blog: Comparison of eight mainstream NoSQL databases NoSQL is a brand new revolution

or the author. [Original] Compared with relational databases, NoSQL databases can efficiently process unstructured data, such as character files, emails, multimedia, and social media. Some NoSQL databases can run in a distributed environment. Therefore, you can use multiple inexpensive devices to complete the functions of a high-performance server. Some Earliest proposal and use Limitations of relational

This article was translated from distributed algorithms in NoSQL DatabasesThe scalability of the system is the main reason for the development of the NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket, and everything can be plugged in. Although the

. Relational databases create more problems when dealing with these trends. This leads to the emergence of a large number of different techniques to address specific aspects of these problems, which can interact with or replace existing RDBMS-also known as hybrid persistence (Polyglot persistence). Database substitutes are not new, they have been in the form of object Databases (OODBMS), hierarchical databases (such as LDAP) for a long time. Howe

Label:Although SQL database is a very useful tool, the monopoly is about to be broken after 15 years of a single show.

Michael Kopp has more than 10 years of architecture and development experience in C ++ and Java/Jee.

Although a mixed-record structure is appropriate for non-relational or NoSQL APIs, because there is no pattern required, developers often face situations where a technique is needed to use a pattern. A consistent pattern definition for some software using SQL (or ODBC, etc.) is required, such as a large number of third-party reporting and analysis tools, including Crystal Reports and Excel, as wel

cannot run well on clusters. You may also build a relational database cluster, but they use shared storage, which is not the type we want. As a result, there is a nosql era that uses Google, Facebook, and Amazon to handle more data transmission. Nosql Era There are already many nosql databases, such as MongoDB, redis

transactions, but also does not support the associated query , why? Because the associated query requires other nodes to provide data sharding , one query needs to mobilize other nodes, so concurrency performance will be very poor.This kind of lightweight distributed database system, which can only guarantee weak consistency, is a NoSQL system , which removes the correlation.NoSQL is the most used when the
