This page contains a list of projects I'm either particularly proud of or feel are worth noting. This list will hopefully keep on growing in future!
Cachex is an in-memory caching system for Elixir, built based on the principles of the cache system inside the Java Guava library. It's extremely fast with support for a lot of extra niceties, and as such is becoming a go-to library for caching needs in Elixir.
Eternal is a utility used in order to keep an ETS table alive forever in Elixir. ETS tables are associated with a process, and would usually terminate if the process dies. Eternal stops this from happening by using a neat owner/heir system with on-demand GenServers.
Tiny is a proof-of-concept JSON parser in Elixir, written with the goal of being minimal and fast while conforming to all JSON standards. As it stands it's comparable to parsers like Poison in terms of speed, but can be considered a good alternative for escript bundles and other embedded builds.
Vessel is a MapReduce framework for Elixir, with support for Hadoop Streaming. Rather than dealing with Hadoop protocols directly, Vessel masks them via a straightforward API. Vessel also includes tools to setup Hadoop projects easily, as well as Mix tasks to make compiling your artifacts painless.
