The traditional core database of the bank was localized for the first time

To ensure the security of data information , Autonomous control is also one of the most urgent promotion strategies of the financial industry , But for the sake of stability , Domestic distributed databases are mostly used in the Internet core and related peripheral systems , There are many kinds of business 、 There has been no precedent in the traditional core of complex processes .

Zhangjiagang rural commercial bank is the first time to adopt domestic distributed database . Its new generation core system uses Tencent cloud TDSQL To carry core business data , So , Zhangjiagang bank spent more than a year on a large number of technical verification .

In the process of system construction , Zhangjiagang bank and Tencent cloud , Fully integrate the scene differences between traditional business and Internet business , Jointly complete the application compatibility transformation and database upgrading and optimization of the new generation core system , We have also jointly formulated TDSQL And centralized database data quasi real-time synchronization strategy , As a solution .

After a series of preparations , Build a database architecture with high availability and strong consistency . Zhangjiagang bank has also become the first commercial bank in China to adopt domestic distributed database in the traditional core system .

On the performance , Based on Tencent cloud TDSQL Our new core system performs well .

High frequency account transactions take time in 300 In milliseconds , Query transaction takes time in 100 In milliseconds ,20 Within seconds 1 Ten thousand batch distribution and withholding business , It takes a lot of time at the end of the day 14 minute , It takes time to settle the deposit interest 11 minute , Loan interest settlement takes time 3 minute …… When batch business is in progress , The database load is kept at 10% following .

secondly , Tencent cloud TDSQL It also gives full play to the advantage of online horizontal expansion of distributed database , When the follow-up business development of Zhangjiagang bank needs , Just add hardware resources , It can automatically scale horizontally to eliminate performance bottlenecks .

Besides , Tencent cloud TDSQL Provided “ Red Rabbit ” and “ Magpie ” The system provides rich tools for automatic operation and maintenance of database , It greatly solves the problem of operation and maintenance efficiency of traditional centralized database .

“ Red Rabbit ” The platform can provide display of hundreds of monitoring indicators ;“ Magpie ” It can easily deal with lock conflicts 、 Index missing 、 Database exceptions such as failover .

For the previously encountered low database throughput , High machine load , Slow business response, etc , Zhangjiagang rural commercial bank has never encountered . The architecture adopts the mode of one main and three standby , Tencent cloud distributed database well supports popular financial products 、 seckill 、 Red envelopes 、 Rush to buy and other massive online customer traffic “ Small high frequency transactions ” demand , Integration with Internet finance business , Effectively enhance the competitiveness of banks .

Four scenarios ensure stability 、 Security 、 Efficient
