Pogreb

Docs Build Status Go Report Card Codecov

Pogreb is an embedded key-value store for read-heavy workloads written in Go.

Key characteristics

  • 100% Go.
  • Optimized for fast random lookups and infrequent bulk inserts.
  • Can store larger-than-memory data sets.
  • Low memory usage.
  • All DB methods are safe for concurrent use by multiple goroutines.

Installation

$ go get -u github.com/akrylysov/pogreb

Usage

Opening a database

To open or create a new database, use the pogreb.Open() function:

package main

import (
    "log"

    "github.com/akrylysov/pogreb"
)

func main() {
    db, err := pogreb.Open("pogreb.test", nil)
    if err != nil {
        log.Fatal(err)
        return
    }   
    defer db.Close()
}

Writing to a database

Use the DB.Put() function to insert a new key-value pair:

err := db.Put([]byte("testKey"), []byte("testValue"))
if err != nil {
    log.Fatal(err)
}

Reading from a database

To retrieve the inserted value, use the DB.Get() function:

val, err := db.Get([]byte("testKey"))
if err != nil {
    log.Fatal(err)
}
log.Printf("%s", val)

Iterating over items

To iterate over items, use ItemIterator returned by DB.Items():

it := db.Items()
for {
    key, val, err := it.Next()
    if err == pogreb.ErrIterationDone {
        break
    }
    if err != nil { 
        log.Fatal(err)
    }
    log.Printf("%s %s", key, val)
}
