Fast and opinionated leveldb interface.
- It does not support any encoding (works with buffers).
- It allows for fast insertion and lookup through
putMany
andgetMany
If you need encoding, iteration and other goodies check out level.
$ npm install --save poziomka
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
});
