beaker

中文|english

beaker is a distributed key-value database under development for learning Rust/Database/Distributed System.

Usage

If you're a Rust programmer, build and it with cargo.

# run the database server at root path with log at info level
RUST_LOG=info cargo run --release --bin server -- --root-path $path

# run command line
cargo run --release --bin cli

# apply command use cli
get key
set key val
del key
ping msg

# or using src/client in crate to apply command
async {
    let client = Client::connect($addr).await?;
    client.ping(None).await?;
}

If you want to install it, using cargo install --path ..

If you want in uninstall it, using cargo uninstall beaker.

Repository content

Guide to modules:

• src/engine: A lsm-tree-based storage engine like leveldb.
• src/server: A implementation of database server.
• src/cmd: A redis-like command library.
• src/cli: A command line client tool.
• src/client: Rust Database Client.
• src/resp: A RESP protocol for exchanging data between client and server.
• src/raft: A RAFT protocol for exchanging data between one server node and another.

Milestones

Basic functional

• Support set/get/del command.

Standalone infrastructure

• lsm tree based kv storage

  • A sstable implementation
  • A manifest for managing sstables and logs
  • Background task, sstable compact/log dumping/expire file cleaning...
  • Database interface
• Resp protocol
• Database server
• Rust client
• command-line client tool
• gentle shutdown

Distribution infrastructure

• Raft protocol (brunch beaker-v0.2.0)
  • leader election
  • log replication
  • snapshot installation
  • configure modification
