Persival - persisten key value store in Go

Persival is an in-memory pseudo key-value storage, very efficient to keep list of records with small amount of data, when there's no need of searching for the values nor keys.

Philosophy

Persival follows those simple rules:

• No user-defined keys are allowed, system MUST decide under what key the value will be stored.
• All the data SHALL always be kept in the memory.
• Persistency SHALL be provided only via logging.
• Activity log SHOULD be merged after it reaches certain size.
• Search for the values CAN NOT be performed.

Storage implementation

So far it's only proof of concept, so all the data is stored as a gob encoded stream.

Installation

Use the go install tool:

$ go install github.com/nu7hatch/persival

Usage

package main

import "github.com/nu7hatch/persival"

func main() {
    bucket, _ := persival.NewBucket("./mybucket.bkt", 0)
    k1, _ := bucket.Set("hello")
    k2, _ := bucket.Set("world")
    bucket.Update(k2, "hurra")
    bucket.Delete(k1)
    bucket.Close()
}
