SnappyDB

A fast and lightweight key/value database library for Android

Introduction

SnappyDB is a key-value database for Android it's an alternative for SQLite if you want to use a NoSQL approach.

It allows you to store and get primitive types, but also a Serializable object or array in a type-safe way.

SnappyDB can outperform SQLite in read/write operations.

SnappyDB is based on leveldb and use snappy compression algorithm, on redundant content you could achieve a good compression ratio

Usage

try {
   DB snappydb = DBFactory.open(context); //create or open an existing databse using the default name

   snappydb.put("name", "Jack Reacher"); 
   snappydb.putInt("age", 42);  
   snappydb.putBoolean("single", true);
   snappydb.put("books", new String[]{"One Shot", "Tripwire", "61 Hours"}); 

   String   name   =  snappydb.get("name");
   int      age    =  snappydb.getInt("age");
   boolean  single =  snappydb.getBoolean("single");
   String[] books  =  snappydb.getArray("books", String.class);// get array of string

   snappydb.close();

   } catch (SnappydbException e) {
 }

With SnappyDB you could seamlessly store and retrieve your object/array, it uses Kryo serialization which it faster than regular Java serialization.
