Tape - A lightning fast, transactional, file-based FIFO for Android and Java.

Java

A lightning fast, transactional, file-based FIFO for Android and Java. QueueFile is a lightning-fast, transactional, file-based FIFO. Addition and removal from an instance is an O(1) operation and is atomic. Writes are synchronous; data will be written to disk before an operation returns. The underlying file is structured to survive process and even system crashes and if an I/O exception is thrown during a mutating change, the change is aborted.

Essentials - General purpose utilities and hash functions for Android and Java (aka java-common)

Java

Essentials are a collection of general-purpose classes we found useful in many occasions. This project is bare bones compared to a rich menu offered by Guava or Apache Commons. Essentials is not a framework, it's rather a small set of utilities to make Java standard approaches more convenient or more efficient.

MapDB - Embedded Database Engine

Java

MapDB is an embedded database engine. It provides Maps and other collections backed by disk or memory storage. It offers excellent performance comparable to java collections, but is not limited by GC overhead. It is also a full database engine with storage backends, transactions, cache algorithms, expiration and many other options. MapDB provides concurrent Maps, Sets and Queues backed by disk storage or off-heap memory.

Boon - Low Ceremony. High Productivity. A real boon to Java to developers!

Java

The main goal of Boon is to reduce the productivity delta between Java and Python/Groovy/Ruby. The idea is to just create a lower ceremony APIs. Less Java like APIs, and more getting things done quickly APIs. If reading a file takes one line of code in Ruby/Python/Groovy, then it will also in Java. If slice notation is part of those language, then Boon will have it to.

FastTuple - Generates heterogeneous collections of primitive values and ensures as best it can that they will be laid out adjacently in memory

Java

FastTuple is a library for generating heterogeneous tuples of primitive types from a runtime defined schema without boxing.

SmoothieMap - A gulp of low latency Java

Java

SmoothieMap is a java.util.Map implementation with worst put(k, v) operation latencies more than 100 times smaller than in ordinary hash table implementations like java.util.HashMap.
