kvdbd

Daemon that enables reading/writing of flat-file key/value databases available via HTTP API, using REST/JSON or Protobufs.

Goals

• "NoSQL databases go from filesystem to docker microservice"
• Written in safe rust
• Can be queried by stock HTTP clients
• Modern HTTP service with threads, HTTP/2 etc.
• Beyond Get/Put/Delete, expose db-specific operations such as transactions or batch-update.
• Access multiple databases simultaneously from a single HTTP endpoint.
• Support multiple database back-ends (sled, lmdb, more soon)
• Docker-friendly Zero configuration mode

Documentation

• Requirements: Rust 2018+ and protoc compiler.
• Quick Start: see below
• Configuration: config.md
• Remote HTTP API: api.md

Using kvdbd

From cargo

Standard rust cargo multi-binary setup:

$ cargo build
$ cargo run --bin kvdbd

From docker

Zeroconf docker example, with sled database stored on docker volume dbdata:

$ docker volume create dbdata
$ docker run --rm -p 8080:8080 -v dbdata:/data jgarzik/kvdbd \
    kvdbd --bind-addr 0.0.0.0 --sled /data/sled.db
$ curl http://127.0.0.1:8080/ | json_pp

Testing

Integration testing is performed via a separate binary, tester.

$ cargo run --bin tester
