Crate kvlite

A key-value store backed by your local file system.

The underlying hashmap uses an inefficient hashing algorithm to place keys and values into large and unoptimized buckets that it reads/writes from a file.

The file size is very large, and does not re-allocate memory. Also, the hashmap doesn’t resize its keyspace. I may or may not fix these things.. this project was mostly just to learn Rust.

Reads are something like 2k QPS, writes 500 QPS. It’s thread- and process-safe (probably).

Installation

Add this to your Cargo.toml:

[dependencies]
kvlite = "0.1.2"

Examples

extern crate kvlite;

use kvlite::FileHashMap;

let kv = FileHashMap::new("myfile.kvlite");

kv.insert("foo", "bar");

let foo = kv.get("foo").unwrap();

println!("foo: {}", foo);  // prints: "foo: bar"

Re-exports

pub use hashmap::FileHashMap;
