Sounds like you’re having fun. Martin’s book is a fantastic reference for building these types of systems.
Once you have a working single-node system you can experiment with making it distributed for scalability and fault-tolerence. It looks like disk_log
supports distribution, but likely not useful because it doesn’t guarantee writes go to all nodes:
A collection of open disk logs with the same name running on different nodes is said to be a distributed disk log if requests made to any of the logs are automatically made to the other logs as well.
It is not guaranteed that all log files of a distributed disk log contain the same log items. No attempt is made to synchronize the contents of the files.
