It is based on H-Store and claims to be 45 times higher than the current throughput of database products, and has high scalability.

Label:Original address: http://tech.it168.com/a2014/0929/1670/000001670840_all.shtml "IT168 Review" the traditional relational database was born without taking into account today's booming mobile, social, and big data load types, and is not suitable for handling extreme-scale processing tasks. But you don't have to worry, 16 professional companies have brought us their respective next-generation NoSQL and Newsql options. Why are companies increasingl

Newsql is the abbreviation for a variety of new scalable/high-performance databases, which not only have NoSQL storage management capabilities for massive amounts of data, but also maintain a legacy database that supports acid and SQL features. Newsql is a new type of relational database management system that seeks to provide the same extended performance as the NoSQL system for OLTP (read-write) workloads

The term newsql is presented in a research paper by 451 Group's analyst Matthew Aslett. It refers to a new type of database system that challenges old database vendors. Newsql is the abbreviation for a variety of new scalable/high-performance databases that not only have NoSQL storage management capabilities for massive amounts of data, but also maintain traditional database support for acid and SQL feature

case,Nosql developers have realized their errors and added SQL Functions. But what I really want to discuss is the so-calledNewsql Database. These databases have been designed to contain SQL interfaces (instead of those added later) from the very beginning, and do not require the relational storage engine at the lower layer. The latest newsql database is voltdb, another file of Michael Stonebraker. It is a standard relational database, but removes

vendors have made great strides in addressing these issues, and their solutions are called eventual consistency. As for Newsql, why not use modern programming languages and techniques to create a relational database with no drawbacks? This is the way many newsql suppliers have started. Other Newsql companies have created an enhanced MYSQL solution.Hadoop is a co

Today, we have completely abandoned the traditional relationship. Database And busy using emerging nosql Data Library may not be a reasonable choice. On the contrary, the improved SQL (Structured Query Language) system may adjust some technical details.

C # Upgrade with NewSQL -- TiDB entry,I. background During the previous attempt to CockroachDB (the portal here: http://www.cnblogs.com/Zachary-Fan/p/cockroachdb_net_csharp.html), it was found that migrating from a conventional RDBMS was almost impossible, so I started to look at NewSQL, which has been quite popular in the past two years. It is also a product made by Chinese people. It is no less popular th

In the previous article, "from architectural features to functional defects, re-understanding of the analytical distributed database", we completed the different "distributed database" of the horizontal analysis, this article Ivan will talk about the second part of the disassembly, combined with the difference between NoSQL and Newsql, from the portrait of the OLTP scenario "distributed Key technical points of the implementation plan.

Voltdb is a revolutionary new database product known as the newsql database. It is based on the H-store, claiming to be more than the current database product throughput of multiple times, but also a high scalability. Its characteristics mainly include the following points:? High Throughput, low latency: through in-memory computing, stored procedures and serial data access implementations. ? Scalability : Automatic partitioning and replication, g

jointly by a subordinate server (slaver) under F1.Working with Remote DataIn F1, the join command in SQL requires reading data from multiple datacenters, which leads to network latency, with data bulk transfer (batching) and pipelined operations (pipelining).Data calculation is usually calculated as part of the calculation is output, reducing the waiting time. The advantage of this is that parallelism is efficient and reduces storage buffering, but the disadvantage is that data cannot be sorted

compared NoSql with NewSql in the previous stage and thought that NewSql may be a better solution for the current project. Through the configuration of the background database software, the implementation meets the high-capacity concurrency requirements without having to make any modifications to the existing Code. This solution seems better than NoSql. It's just that programmers usually like to solve prob
