数据库中间件cobar的作者,你好 我们是一家科技公司,有幸使用了这款优秀的开源软件 感谢作者的贡献,我们使用的这段时间一直挺稳定的 但最近生产环境遇到了一个问题,影响范围挺大的,想请教下你,具体情况如下: 一、环境 MySQL 8.0.28 cobar-1.2.8 wordpress 6.0 wordpress网站通过cobar数据库中间件去连接后端真实MySQL数据库 MySQL数据库和文章表均为utf8mb4编码 二、问题描述 编辑wordpress后台文章内容,插入emoji表情(🔥👍🏆)时,无法保存和查看emoji表情 ![image](https://github.com/alibaba/cobar/assets/8329353/58a181d3-708d-4008-b115-cb9d74056b73) m ![image](https://github.com/alibaba/cobar/assets/8329353/111fe19b-9990-4be4-bdc5-25b35acbd5fc) 三、初步排查: 如果wordpress网站直连MySQL数据库,就没这个问题 四、需要的帮助: 需要确认cobar最新版本1.2.8是否原生支持emoji表情和utf8mb4编码 如果不支持,可以通过什么方式来让其支持 期待你的帮助和解答,感谢!

driver的URL配置为jdbc:cobar://xx.xx.xx.3:8066,xx.xx.xx.4:8066/dbtest。 在xx.xx.xx.3 和xx.xx.xx.4这两台cobar server都运行正常时,可以正常实现负载均衡 关掉xx.xx.xx.3后,就无法获取到连接了,难道不应该是xx.xx.xx.3挂了,就直接连接xx.xx.xx.4吗?

阿里是如何部署cobar集群、又是如何应用的,简单介绍一下,谢谢!
