Abstract ： stay GaussDB(for Cassandra) Under the support of ,HUAWEI Tag Anti loss Genie shows a very strong core competitiveness .

This article is shared from Huawei cloud community 《 All things can be Cassandra——HUAWEI Tag Behind the fairy database 》, author ：GaussDB database .

What is? HUAWEI Tag？

7 month 4 Japan , Huawei's first anti loss product ——HUAWEI Tag The anti loss spirit is officially unveiled . Don't underestimate the weight of this product only 6g Small pendant , Supporting loss prevention reminders is nothing , The endurance time was as long as a whole year ！ Yes, of course , Its ability is more than that ：

It can be seen that ,HUAWEI Tag The function of is comprehensive , Compared with peer products, it is quite attractive . How are these core functions realized ？

HUAWEI Tag How to achieve long-distance loss prevention ？

We can get to know something about HUAWEI Tag How it works ：

First, Huawei is composed of hundreds of millions of Huawei equipment “ lookup ” The Internet ;
Secondly, the location information is updated through the Huawei device network .

Here are HUAWEI Tag Through Huawei ” lookup ” Schematic diagram of network connection ：

Pictured ,HUAWEI Tag The hardware is mainly through Bluetooth and Huawei ” lookup ” Network communication , And then regularly report the current location information . So here comes the question , If HUAWEI Tag Millions of users , It means there are millions at the same time HUAWEI Tag The equipment passes Huawei ” lookup ” Network updates location information , At the same time, you should update your location information regularly .

In this case , Massive data storage and high concurrent writing will become the norm . What kind of database can meet such requirements ？ This has to say that it has ultra-high read-write performance GaussDB(for Cassandra) 了 .

GaussDB(for Cassandra) What is it? ？

GaussDB(for Cassandra) It is a Huawei self-developed 、 Distributed cloud database with computing storage separation architecture , In high performance 、 High availability 、 Highly reliable 、 High security 、 On the basis of elastic expansion and contraction , Provides one click deployment 、 Backup recovery 、 Monitoring alarm and other service capabilities ; And highly compatible with open source Cassandra Interface , Provide high read / write performance .

Why GaussDB(for Cassandra)？

GaussDB(for Cassandra) Specially optimized for excellent write throughput , At the same time, it provides multidimensional query of massive data 、 Text retrieval 、 Fuzzy query and other capabilities , Compared to the open source version , Performance can be improved 3 times , Be able to satisfy easily HUAWEI Tag Massive data storage and high concurrent write requirements .

In terms of configuration ,GaussDB(for Cassandra) It also has many advantages , Number of operating nodes 10000+, Total data 5PB+, On-line OPS 1000 ten thousand +, Average service delay 4ms, These features can be greatly improved HUAWEI Tag Operating efficiency , Enhance user experience .

summary

At present ,GaussDB(for Cassandra) It has been widely used in IoT、 meteorological 、 Internet 、 Games and many other fields , For user behavior analysis 、 User portrait 、 Social entertainment , And massive real-time data processing and other scenarios are extremely friendly , Accumulated rich practical experience . stay GaussDB(for Cassandra) Under the support of ,HUAWEI Tag Anti loss Genie shows a very strong core competitiveness , It also has only 99 Yuan can have the ultimate cost performance , So that every user can feel at ease , It's easy to find things ！
