nosql scalability

. Delete secondary indexes of a table, rewrite the query so that it only uses the primary key index; 7. Database sharding; this method is complex and costly to maintain; and it is costly to re-split when the data size increases again, limited secondary scalability; Ii. RDBMS and NoSQLIn actual use, as long as the architecture is proper, relational databases can fully serve various levels of data storage applications, for example, Facebook and Google e

In terms of creating, communicating, accessing content, sharing information, and buying products, the rapid expansion of a new generation of internet-based services, such as e-mail, blogs, social media, search, and E-commerce, has actually redefined the behavior and trends of WEB users. As the number of these systems continues to grow, IT professionals are witnessing the scaling up of data and data consumed, and growing scalability requirements and ne

Scalability (extensibility) is a design indicator of the computational processing power of software systems, high scalability represents a kind of elasticity, in the expansion of the system growth process, the software can guarantee exuberant vitality, through very few changes or even just the acquisition of hardware equipment, can achieve the entire system processing capacity of linear growth, Achieve high

hardware equipment, can achieve the entire system processing capacity of linear growth, Achieve high throughput and low latency performance. Vertical scalability-adding resources to the same logical unit to improve processing power. Examples include adding CPUs to an existing server or adding a hard disk to an existing Raid/san store to increase the amount of storage. Horizontal scalability--add more resou

= True ){DB. Commit (); // Commit transactions } Else {DB. rollback (); // Failed to roll back } The above code may seem a little troublesome, but you only need to make a unified encapsulation on the DB class or ORM layer to achieve reuse. Other code does not need to be modified. This architecture adds an auxiliary nosql storage layer to the original mysql-based database architecture, with a small amount of code and a low technical di

Modify tablespaces (modify the automatic scalability of data files) and Data scalabilityModify tablespaces (modify the automatic scalability of data files)When creating a tablespace, you can set the automatic scalability of the data file. When a new data file is added to the tablespaceYou can set Automatic scalability

original MySQL database-based architecture, with a small amount of code and little technical difficulty, but has a significant impact on scalability and performance. Only when the program is written to the MySQL database and written to a NoSQL database, so that MySQL and NoSQL have the same mirrored data, and in some places where you can query based on the prima

Recently need to use Redis in C #, found on the Redis official website Servicestack.redis, finally in the test found that this is a pit, 4.0 has been charged, the latter had to find the final version of the 3 series, the final test found that there is still a bug or I will not use. There is no way, it is best to find the Stackexchange.redis, support asynchronous client, it is said that performance is better than Servicestack.redis, and it is said that the stack overflow is also used by this clie

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-s

Do a year's freshman year project, for relational database structure or some understand, sometimes still feel that the two-dimensional table is not very comfortable. After reading an article, there is a preliminary understanding of NoSQL (Https://keen.io/blog/53958349217/analytics-for-hackers-how-to-think-about-event-data). This article is written very well, indeed written out in the actual situation of the "NoSQL
