I think there do not have a clear describe regard to seata component and their respective configration.
Yea, you guys wrote a documentation but it just describe every option's mean.
Yea, you guys impletment various of config and registy center but it's not clearly about their's usage.
But I do not recomment wrote a documentaion all in one.

Let's have a look about what happen
Fristly I download a seata server package and found there have 2 files about the configruation.
One is conf/application.yaml which one I think is a configuration for seata sever seems like our springcloud's application.yml.
One is script/config-center/config.txt which one is refer to seata offical documentation

question 1:
参数同步到配置中心使用demo
I did it.

And then It looks strange. My first impression of this is something maybe really wrong. but ,I don't know.
question 2:
There do not have a documentation about application.yaml Just have a example file .
seata.config.nacos.data-id for what?
Does this prove someting about question one ,I don't know.

seata:
  config:
    # support: nacos 、 consul 、 apollo 、 zk  、 etcd3
    type: file
    nacos:
      server-addr: 127.0.0.1:8848
      namespace:
      group: SEATA_GROUP
      username:
      password:
      context-path:
      ##if use MSE Nacos with auth, mutex with username/password attribute
      #access-key: ""
      #secret-key: ""
      data-id: seataServer.properties

I'm still confused about where this configuration should be placed,and when they will be loaded and use.
