[API Change] Move the user configuration to authority rule

[tristaZero]

Hi, community,

This issue is to do API change of server.yaml of ShardingProxy. More precisely to say, we plan to move the user configuration to the authority rule module. Hope you can have a try and get 👍 .

Target

Please change the configuration of server.yaml from

users:
  - root@%:root
  - sharding@:sharding
rules:
  - !AUTHORITY
    provider:
      type: NATIVE

TO

rules:
  - !AUTHORITY
    users:
      - root@%:root
      - sharding@:sharding
    provider:
      type: NATIVE

How?

There are two necessary sections to achieve it.

The refactoring of Yaml configuration

1 Move users from YamlProxyServerConfiguration to YamlAuthorityRuleConfiguration
2 Move YamlUsersConfigurationConverter handling from YamlProxyConfigurationSwapper to AuthorityRuleConfigurationYamlSwapper
3 Move users from ProxyConfiguration to AuthorityRuleConfiguration
4 Remove persistUsers(users, isOverwrite); of RegistryCenter
5 Move the relevant Unit test classes to corresponding packages.

The change of User and authority initialization

1 Remove users, which has been stored in AuthorityRuleConfiguration from MetaDataContextsBuilder
2 Remove users from the signature of ShardingSphereRulesBuilder.buildGlobalRules()
3 Put users into AuthorityRule from AuthorityRuleConfiguration
4 Fix the Unit tests

Hi guys, @huanghao495430759 @zhujunxxxxx

Hope you have an enjoyable holiday!

I have to say there are two important and challenging issues to seek excellent contributors from the community.
Based on two of you's great previous contribution and experience, I assume you are eligible to deal with these difficult issues. So please excuse me for occupying you here. :)

I just wonder whether you are interested in this issue and #10252 and willing to take charge?

Here are some pointers FYI,

• [API Change] Move the user configuration to authority rule #10251 and [Enhancement] Support authority rule governance through different proxies #10252 have some of the associations.
• [Enhancement] Support authority rule governance through different proxies #10252 is difficult than this one.
• Some sub-tasks of [Enhancement] Support authority rule governance through different proxies #10252 rely on this one.

If you are not available, please still tell me so that I can assign these issues to others. Thanks.

Hi @zhujunxxxxx ,
Glad to see you stepping forward. Which one do you want to try? Or both?

[huanghao495430759]

OK, Can I try it too ?

[gloriawish]

I want to try #10251.

@zhujunxxxxx Hey, welcome.
@huanghao495430759 I will assign #10252 to you. Since you have done something to do with that, I suppose that issue will become simpler for you. :)
