tera client客户端连接问题

想问一下
1、若部署1000个tablenode，client sdk是直连tableserver的么，这个是长连接么？
在这种情况下，如果有上千个client该怎么办呢？

或者说存在大量连接时，得使用tera proxy?

2、client sdk如何发现故障节点，并踢出该节点，如果是通过zk发现，会不会导致时延上的丢数据？

The issue names the client SDK, tableserver, Tera proxy, and ZooKeeper-based discovery but no source files or tests. Start by locating the SDK connection and node-discovery entry points, then trace how failed nodes and large numbers of connections are handled. Done means documenting the connection model, when a proxy is needed, and the failure and data-loss behavior.
