1. Each worker thread contains a Lua VM, the Lua VM shared with all connections on this thread. This VM specifically executes the EVAL_RO command.
2. Each connection's commends is pipeline runing.
3. Each worker's connetions send a lot of commands to kvrocks at the same time, but the same thread will exec command one by one. So the same thread can share one Lua VM.

Cool, it's good to separate the Lua vm to improve the performance in the readonly mode.
You can go ahead implementing this if you're willing to do this.
