Poziomka NPM | npm.io

poziomka

Fast and opinionated leveldb interface.

It does not support any encoding (works with buffers).
It allows for fast insertion and lookup through putMany and getMany

If you need encoding, iteration and other goodies check out level.

Install

$ npm install --save poziomka

Usage

var Poziomka = require('poziomka');

let db = new Poziomka('/path/to/my/db');

// no encoding/decoding - poziomka works with Buffers
let keys = [2, 3, 4].map(x => Buffer.from([x]));

db.open(function(err) {
  if (err) {
    // something went wrong
  }
  // database is not open
});

// keys and values have to be Arrays of Buffer's
db.putMany(keys, values, function(err) {
  // for each key in an
});


// keys and values have to be Arrays of Buffer's
db.getMany(keys, function(err, values, missing) {
  if (err) {
    // leveldb error
  }
  if (missing) {
    // some of the keys were not in DB
    // missing has indexes in the keys array, so to print the keys
    console.log('Missing keys:', missing.map(i => keys[i]));
  }
  // empty Buffer is returned for each missing key
});

db.removeMany(keys, function(err) {
  // keys are now deleted
});
