dovii

Namesake parachromis dovii

A key-value data store used for learning more about the internals of a database. The goal is to incrementally improve the robustness and speed of the database, ideally reaching a point of an eventually consistent data store like Cassandra or Redis.

How to run

• Need to have a local Docker daemon running and docker-compose installed
• Run with 3 dovii instances docker-compose up --scale dovii=3

API

GET

• curl --header "Host: dovii.local" http://localhost/<KEY>

SET

• curl --header "Host: dovii.local" -X POST http://localhost/<KEY>/<VALUE>

Changelog

• String keys and values stored in memory
• String keys and values stored in json on disk
• Bitcask support
• Deploy multiple instances with docker-compose, load balanced behind traefik
  • At this point the system does not return correct values for GETs, this is expected, now we do RAFT to get values consistent across cluster
• Use hashicorp/raft to guarantee consistency across nodes
