What is NoSQL?

A NoSQL (often interpreted as Not only SQL) database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases.

Tencent NoSQL High-speed Storage is a Tencent-developed in-memory and durable storage service in distributed key-value structure with extremely high performance.

  • As designed for final ground storage, it guarantees database level processing and continual service capacity.

  • Supports Memcached, Redis as well as MongoDB.

  • Resolves issues of data reliability, distribution and consistency for in-memory, making development of mass accessing simple and fast.


Advantages

Low cost

High performance
One single cache server supports 500 thousand/second accesses, and one single table allows access of ten million times/second at most.

Low delay
The average delay is about 1ms.

Safe and reliable
No data will get lost when restarting the machine. The dual hosts’ hot standby, master-slave switching is transparent to business. Since it is deployed cross rack and switch, Tencent NoSQL storage is capable of data correction during disaster.

Mature and Stable
