Popple is a distributed, highly available, general purpose key/value database.

Features

• In-memory database for fast reads and writes using b-tree
• Embeddable with a simple HTTP API
• ACID semantics with locking transactions that support rollbacks
• A flexible key/value store enables storing dynamic data, like redis sds
• Ensure high availability and consistency using the Raft protocol
• Simple to use command line or optional configuration file
• Grpc and http serve the same port

Quick Start

Installing

To start using Popple, install Go and run make build in root source folder. This will generate an executable file named popple in ./bin folder. You can move it to any where in your PATH.

Usage

Run popple --help or popple server --help to view the usage. For example:

Start a Popple server

Usage:
  popple server [flags]

Flags:
      --cluster string    Define cluster servers. The format is sid:address pairs, comma separation. For example, "0=127.0.0.1:8876,1=192.168.0.2:8889,2=192.168.0.56:8080"
  -c, --config string     Path to a configuration file.
      --data-dir string   Path to raft log and database file dir. (default "./")
      --dev               Enable development mode. In this mode, Popple runs in-memory and starts. As the name implies, do not run "dev" mode in production. The default is false.
  -h, --help              help for server
      --sid int           Current Server ID. default is 0

The command line arguments are simple and straightforward. For example: To run a single node dev mode server, you just run popple server --dev. The server will select a random port to serve. You can get the port from console:

2023/02/21 11:17:55 DevMode: true
2023/02/21 11:17:55 server[0] listening at [::]:36967

...

Testing

Run make test in root source folder to view high availability on conditions like leader down, network partition...And so forth.
