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
});
