## What is DTM ## What is DTM
DTM is the first distributed transaction management framework in golang. Unlike other frameworks, DTM provides extremely easy access to HTTP and gRPC, supports multiple language bindings, and handles tricky problems of unordered sub-transactions at the framework level.
