Kunlunbase meetup is waiting for you!

7 month 2 Japan （ Saturday ）,KunlunBase on-line MeetUP I'm waiting for you ！

Welcome to Saturday afternoon KunlunBase studio , Our technical experts will explain to you KunlunBase The design idea and implementation of the characteristic distributed task framework 、 applied technology , as well as KunlunBase Unique read-write separation scheme and its unique advantages over other types of functional components . Learn to exchange and learn software design and development technology and database system application and management technology , Come on KunlunBase studio ！

15：00-15：40

lecturer ：Summer（ Database system technologist ）

The theme ：《KunlunBase Introduction to distributed task coordination framework 》

Content introduction ：KunlunBase（ Kunlun database ） As a distributed database product , Native has the need for multiple physical devices to work together . Many cluster level operations, such as capacity expansion , Retreated , Add slices (storage shard), Increase / decrease calculation node , Increase or decrease storage nodes , Redo the standby machine , data shuffle And so on need to be completed on different physical devices .KunlunBase These tasks in are usually composed of multiple or parallel or serial steps , And different tasks need to be executed in parallel . In order to make this distributed collaborative task complete reliably, it has both scalability and concurrency , The team built a distributed task execution framework . After our practice and continuous improvement , This framework can well Abstract tasks with complex temporal dependencies , To achieve a high degree of concurrency , Easy to program , Task status is observable , And good packaging and modularization . This technology sharing introduces this distributed task processing framework and its application in KunlunBase Application in .

15：40-16：20

lecturer ： He Chuangxin （ Zetuo technology pre-sales technical expert ）

The theme ：《KunlunBase Read write separation scheme 》

Content introduction ： Database read-write separation technology is widely used in production systems , By executing read-only queries on the standby machine, you can make full use of the hardware resources of the standby machine , Avoid read-only queries affecting the write performance of the primary node . There are many implementation schemes for read-write separation ： Based on Applications 、 Based on database driver 、 Based on middleware , Some of these schemes usually need to modify the application code , Some schemes ignore the requirements of data consistency , This leads to inaccurate query results .KunlunBase The database cluster passes through KunlunServer（ Computing node ） Read and write separation , Easy to use and efficient , The configuration is simple and convenient , There is no need to modify the application code , It can realize the separation of reading and writing transparently , And keep things going ACID attribute . This topic describes KunlunBase The working principle of read-write separation of database clusters , advantage 、 Implementation methods and usage methods , The configuration process of read-write separation is demonstrated by a case .
