Bitcasky

Bitcasky is a Rust implementation of the Bitcask key-value store. Bitcask is an ACID-compliant, append-only key-value store that provides high write throughput. It is optimized for write-heavy workloads, and is commonly used for applications such as log storage and time-series data.

Features

• Append-only storage for durability and consistency
• Memory-mapped files for efficient I/O
• Key-value storage with O(1) read and write performance
• Storing automatically expired values

Usage

Basic usage

To use Bitcasky, simply add it to your Cargo.toml file:

[dependencies]
bitcasky = "0.1.1"

Then, in your Rust code, import the bitcasky crate and start using the key-value store:

use bitcasky::Bitcasky;

fn main() {
    let mut db = Bitcasky::open("/path/to/db", BitcaskyOptions::default()).unwrap()

    db.put("key", "value").unwrap();
    let value = db.get("key").unwrap();

    println!("{:?}", value);
}

Save expirable values

use bitcasky::Bitcasky;

fn main() {
    let mut db = Bitcasky::open("/path/to/db", BitcaskyOptions::default()).unwrap()

    db.put_with_ttl("key", "value", Duration::from_secs(60)).unwrap();
    let value = db.get("key").unwrap();

    println!("{:?}", value);
}
