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

--sid int Current Server ID. default is 0The 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
...Run make test in root source folder to view high availability on conditions like leader down, network partition...And so forth.
