Is your feature request related to a problem?

• Yes, refer to Add GraalVM Reachability Metadata and corresponding nativeTest for Consul integration shardingsphere#29588 and Improve GraalVM Reachability Metadata and corresponding nativeTest related unit tests shardingsphere#29052 .

Describe the feature you would like.

• com.ecwid.consul:consul-api has not released a new version for 4 years, which has led to issues like Some API is deprecated in version 1.15.x! Ecwid/consul-api#246 and was released in Consul 1.17 .x will be completely unavailable. Issues like Consider replacing https://github.com/Ecwid/consul-api with Interface Clients spring-cloud/spring-cloud-consul#475 are actively being moved away from com.ecwid.consul:consul-api.

• Issues like Add client support for Watches Ecwid/consul-api#19 expose that com.ecwid.consul:consul-api does not encapsulate the watches API at all, refer to https://developer.hashicorp.com/consul/docs/v1.17.x/dynamic-app-config/watches . This resulted in shardingsphere-plugin-mode-cluster-repository-consul even operating the index manually, which caused a lot of confusion in further maintenance.

• According to an investigation at Add GraalVM Reachability Metadata and corresponding nativeTest for Consul integration shardingsphere#29588 , the Consul integration is currently unavailable, again requiring further investigation.

• This issue target is handling two subtasks.

  • Replaces com.ecwid.consul:consul-api with com.orbitz.consul:consul-client.

    • Although com.orbitz.consul:consul-client has been archived, its last release is later than com.ecwid.consul:consul-api. It also provides an encapsulation of the watches interface, simplifying the use of Consul Index handling, which helps align the operations of existing Zookeeper integration implementations in ShardingSphere.
    • Although there is a community branch as org.kiwiproject:consul-client, there is nothing that can be done about ShardingSphere considering that Update minimum Java version to 11 kiwiproject/consul-client#39 improves the JDK compiled version to JDK11.

  • Replaces com.orbitz.consul:consul-client with io.vertx:vertx-consul-client. io.vertx:vertx-consul-client is the only Java Client for Consul currently being maintained. I don't think we should actively encapsulate HttpClient, this kind of thing should be done by a third party.

There hasn't been any activity on this issue recently, and in order to prioritize active issues, it will be marked as stale.

• The current issue is unlikely to be completed before the 5.5.0 release. Consul's integrated wacth() function implementation is broken for unknown reasons.

[linghengqian]

• Due to the impact of Move mode consul to ShardingSphere plugin repository shardingsphere#30288 , this issue is moved to plugin git.

• I will put the current question on hold as I don't want to spend effort on Consul under Business Source License 1.1. This is for personal reasons.
• If anyone is willing to submit a PR to fix the current issue, I will still assist in reviewing and merging.
