when you say "目前只支持eval的方式来跑lua脚本，需要配合TAG使用.", what do you mean exactly, any sample?

对更新单行记录的优化如何保证幂等？

https://github.com/alibaba/AliSQL/wiki/Changes-in-AliSQL-5.6.32-(2016-10-14) https://github.com/alibaba/AliSQL/wiki/AliSQL-Performance-benchmark-for-inventory https://github.com/alibaba/AliSQL/wiki/alisql_ic.lua 看到这里根据hint可以自动提交，但是如何保证幂等性，最简化的做法是根据订单查询流水，如果没有流水则INSERT订单，UPDATE库存，INSERT+UPDATE是在一个事务，订单通过唯一键约束，但是这里更新库存直接提交了，怎么确保是否应该提交，是否是订单重入的请求？

I know the original python version of shadow-socks has the name of `ssserver` py script, and what is `ss-server` here: `ss-server -c config.json -p 80 --plugin v2ray-plugin --plugin-opts "server"`
