Question: about the design choice over raft and others.

First of all I must say great work!!!

The Paxos is only used to elect the master (or re-elect if the master fails). Once a master is established, it coordinates all distributed transactions centrally, which is very fast.

My question is:

• Is Raft able to do this job as fast as Paxos?
• Is there any benefit that raft can't provide?
• Is Bedrock still use Paxos only for elect the master？
• I assume Bedrock use quorum vote to do the distributed transactions centrally？
• The commit logs store in sqlite or Log-Structured Merged-Tree ?
• this projects use asynchronous with coroutine?

David Barrett provide some nice details. My question is :

• The around network traffic between 6 server from 3 region average daily, and the peek bandwidth.

• Bedrock only allow change schema when Cluster has one server(others leave and rejoin late), do you use some kind shard solution ? or just put all user data to one table ? or create new sqlite instance when users number over a certain amount( I assume this is allowed at Cluster mode)?

• Can I use stored procedure without C++ ?
