The document discusses SnappyDB, a key-value database for Android that uses LevelDB and Snappy compression. It provides a Java API and integrates Kryo for serialization. The presentation highlights that SnappyDB is faster than SQLite, especially for large BLOBs, and avoids boilerplate code. Installation can be done through Maven or by copying files, and code examples are provided. Benchmarks show SnappyDB outperforming SQLite with and without transactions.

•
SQLite Sucks!
1Mb BLOB limitation
Boilerplate code
SharedPreferences is not the solution
