@aliensb 为什么呢？

这个标题秀出了你司的优越感吗？

ditto 本身自带内网传输功能，可以打开菜单看看，设置密码即可在局域网内装有 ditto 客户端机器同步剪贴板。

完全一样的情况，马上 30 了，相亲见过很多女生，基本都不是很热情，回复冷淡，而且大多没啥素质。

@Morriaty
下载源码看了一眼，有很多依赖都是来自一个 infini.sh 的站点，然鹅，这个站点已经无法访问了。所以二次开发受阻。

@Morriaty 谢谢老哥，我去围观下

看了 kong 的文档，发现他的 路由能力太弱了，无法解析请求体。

这是我用 fiddler 抓到的包，详细记录了 spark 使用 ESHaghilevelClient 写入数据的 HTTP 报文：

```http

初步想法是解析 ReqBody，然后根据 index 名称拆分为多个 http 请求发到对应的 ES 集群上，最后响应全部结果给客户端。
但是响应的报文格式应该是无法兼容 ESHighLevelClient 。。。

traefik 看上去略显弱势

@tanxnative 如果只有一个集群的话，可以通过分片算法来分发数据，
但是多个集群之间，目前没有现成方案。

@plko345 没在 k8s，在 AWS 服务器上

楼上那么多用触控板的，怎么精确点击，比如要定位到代码的某一行某一列时，难道要用触控板去滑动？左手键盘，右手鼠标，这才是效率最高的姿势吧？

既然 es JAVA 客户端使用 http 协议通信，那么在网关层，可以通过请求的 method 、host 、path 、query params 、reqbody 来动态映射目标 es 集群
