/** Looks like ZooKeeper but stores all data in memory of server process.
* All data is not shared between different servers and is lost after server restart.
*
* The only purpose is to more simple testing for interaction with ZooKeeper within a single server.
* This still makes sense, because multiple replicas of a single table can be created on a single server,
* and it is used to test replication logic.
*
* Does not support ACLs. Does not support NULL node values.
*
* NOTE: You can add various failure modes for better testing.
