fastutil extends the Java Collections Framework by providing type-specific maps, sets, lists and priority queues with a small memory footprint and fast access and insertion; provides also big (64-bit) arrays, sets and lists, and fast, practical I/O classes for binary and text files.

The DSI utilities are a mish mash of classes accumulated during the last ten years in projects developed at the DSI (Dipartimento di Scienze dell'Informazione, e.g., Information Sciences Department) of the Università degli Studi di Milano.

sux4j is an implementation of succinct data structure in Java. It provides a number of related implementations covering ranking/selection over bit arrays, compressed lists and minimal perfect hashing.

MG4J (Managing Gigabytes for Java) is a free full-text search engine for large document collections written in Java.

MG4J (Managing Gigabytes for Java) is a free full-text search engine for large document collections written in Java. The big version is a fork of the original MG4J that can handle more than 2^31 terms and documents.

WebGraph is a framework to study the web graph. It provides simple ways to manage very large graph, exploiting modern compression techniques. The big version is a fork of the original WebGraph that can handle more than 2^31 nodes.
