nosql scalability

aggressively moving into new business categories, including gaming, e-commerce, and security, all of which require high latency conditions. We will also keep an eye on the platform to see if aerospike can be a broader solution. 　Official website:http://www.aerospike.com/ 　Cassandra is leading the way in global scalability competition 　　DBMS Type: Nosql 　　Description: Massively scalable partitioned row sto

Do you really understand the nosql world ?, Nosql world Recently, I want to sort out my nosql knowledge and some nosql databases. One is to deepen your understanding of nosql, and the other is to organize your knowledge to make it more organized. So I started to

) Design for scalability and Autoscale Safety throughout the design always, in each layer Do not worry too much about constraints and failures (such as the ability to deal with each time is not enough, to do is clear understanding of the current design ideas, because the cloud is infinitely extensible, so do one thing after the cloud can be replicated and expand the ability) Multi-factor parallel distributed processing Fu

The scalability of the Web site is designed to allow for the ability to continuously expand and enhance the system's capabilities with minimal impact on existing systems. Here is a detailed description of the "extensibility" and "scalability" concepts that are easy to confuse: Extensibility Performance: infrastructure does not need to change frequently, applications are less dependent or coupled, and can re

creating more columns. These databases are also very suitable for creating prototypes or rapid applications, because this flexibility makes development of new features very easy. 2. NoSQL is easy to achieve Scalability (up extension and horizontal extension) If many users use your applications frequently and concurrently, you need to consider scalable database technology rather than traditional RDBMS. For

Differences between NoSQL and SQL: NoSQL and SQL. About the difference between NoSQL and SQL, NoSQL and SQL simply put: SQL is a structured query language for relational databases, while nosql generally refers to relational databases, and SQL statements cannot be used, no di

stores data as a unit, and is adept at reading the data in columns.High scalabilityColumn-oriented databases are highly scalable, and they are primarily used in situations where large amounts of data are needed, even if the data is increased without reducing the processing speed (especially the write speed). In addition, it is useful to use the advantages of a column-oriented database to update large amounts of data as a batch program's memory. But because the column-oriented database is very d

, the strict and pattern-based methods used by relational databases cannot quickly accommodate new data types, and they are powerless for unstructured or semi-structured data. The data model provided by NoSQL can meet this requirement well. Many applications will benefit from this unstructured data model, such as CRM, ERP, BPM, and so on. They can store data with this flexibility without modifying tables or creating more columns. These databases are a

. SQL is scalable, feature-rich, and proven to solve a variety of challenges-including write-driven fast transactions and deep analysis involving frequent scans.4. SQL can seamlessly interface with data presentation and storage mechanisms. Some SQL systems also support JSON and other structured object formats, resulting in better performance and more functional features than NoSQL scenarios.The term "NoSQL"

Label:In the past, we only needed to learn and use a database technology to do almost all of the database application development. Because the mature and stable relational database products are not many, and for you to choose the free version is even less, so the Internet domain basically chose the free MySQL database. In the rapid development of the WEB2.0 era, we found that the relational database in performance, scalability, rapid data backup and r

transaction changes A, then the B must be changed so that the transaction will still satisfy a+b=10, otherwise the transaction fails.3, I (isolation) IsolationThe so-called independence refers to the concurrent transactions do not affect each other, if one transaction to access the data is being modified by another transaction, as long as another transaction is not committed, the data it accesses is not affected by uncommitted transactions.For example, there is a transaction from a to 100 yuan

enable users to use their knowledge across systems and to support third-party attachments and tools.3. SQL can be extended, and is versatile and time validated, which can solve problems from fast write-driven transmission to scanning intensive in-depth analysis.4. SQL is an orthogonal form of data rendering and storage, and some SQL systems support JSON and other structured object formats, with better performance and more functionality than NoSQL.Although N
