说明一下,dtm和seata有很大不同,dtm一开始就支持HTTP/gRPC这类对云原生友好的协议,dtm本身完全不需要注册中心。因此dtm可以很好的与K8S结合在一起,把dtm当做一个普通的HTTP/gRPC服务进行部署,设定副本数就具备了高可用。
dtm同时也支持微服务协议,例如go-zero,kratos,dapr,以及其他的,对这些微服务协议的支持都在驱动层完成。这些微服务协议支持哪些注册中心,那么dtm就直接支持,直接使用。业务使用时,只需要加载相关的驱动即可。

如果使用的是内部自研的微服务框架,想要把dtm注册到consul、nacos等注册中心,在不改动dtm源码的前提下是否可行?
from dtm.pub.
那么这就相当于让dtm多支持一种微服务协议,过程是,写好了dtmdriver-微服务 驱动之后,提一个PR(一行代码,加载驱动)到dtm,这样就行了。
参考go-zero和kratos等驱动是如何编写的
from dtm.pub.
是不是可以提供更友好方式?比如kratos的服务注册可以按照提供的interface自行实现具体的注册逻辑,然后替换到默认的注册实现,这样服务注册就跟框架自身解耦,就不用往框架仓库提交代码。
from dtm.pub.
你再想想,你业务的代码能否跟微服务框架无关?能否今天用你自研的微服务框架,改天用另一个框架go-zero,然后都不需要重新编译?
dtm要支持一个新的微服务协议,一行代码不改,不重新编译,那么新的微服务协议的逻辑,怎么进入dtm呢?
from dtm.pub.
我先研究下go-zero和kratos的驱动。或许可以实现dtmdriver-consul 、dtmdriver-nacos、dtmdriver-etcd等注册中心的驱动,毕竟使用java的,只是想要把dtm的服务做一个服务发现,发现dtm的http、grpc调用地址
from dtm.pub.
go-zero - etcd 跟 kratos-etcd是不一样的,无法一个dtmdriver-etcd同时支持go-zero和kratos
