I think you should do more understand for nacos database plugin.

paramList.add(tenantId);
final String sqlCount = "SELECT count(*) FROM config_info_aggr WHERE data_id=? AND group_id=? AND tenant_id=?";
return new MapperResult(sqlCount, paramList);
}

这么改似乎目前不会影响用户自定义的插件逻辑,相当于还是一种固定参数的形式。针对分页提供了count的默认实现方法,如果用户想实现自己的count逻辑也可以重写默认实现方法。相当于用户自己实现的数据源插件,count查询提供了入口进行修改。看这么改是否合适;可以review一下我最新一次的提交 @KomachiSion

目前我只更改了一个地方,对sqlcount提供了默认实现,这种方式可行的话我将把其他地方一并更改掉
