Here is a detailed explanation of how to use DTM to help our order system solve the consistency problem 10.2 go zero uses DTMįirst, let's review Chapter V order service Processing logic of Create interface in order rpc service in. Moreover, DTM has deep cooperation and supports distributed transactions in go zero. DTM can greatly simplify the architecture and form an elegant solution.
Most of the transactions of the order system will cross services, so there is a need to update data consistency. Through this series, we hope to take you to quickly develop a mall system by using the Docker environment and go zero on the machine, so that you can quickly start micro services.Ĭomplete sample code: /nivin-studio/go-zero-ma.įirst, let's take a look at the overall service splitting diagram:ĭTM It is a distributed transaction manager developed by golang, which solves the consistency problem of updating data across databases, services and language stacks. The whole series is divided into ten articles, and the directory structure is as follows: We will show you a go zero micro service example in detail through a series of articles.
