TrailDB - Efficient Storing & Processing Event Data
A library, implemented in C, which allows you to query series of events at blazing speed. TrailDB is also optimized for speed of development: Use its simple API with your favorite language, in your favorite environment.

TrailDB's secret sauce is data compression. It leverages predictability of time-based data to compress your data to a fraction of its original size. In contrast to traditional compression, you can query the encoded data directly, decompressing only the parts you need.

ffwd - Event & metrics fast-forwarding agent
A flexible event and metric forwarding agent. It is intended to run locally on the system and receive events and metrics through a wide set of protocols and then forward them to your database. By Spotify. By running locally, it is easily available to receive pushed data from any application or service that is running on the same system. ffwd decorates the received data with system-wide tags or attributes. By doing this, the application generating the data becomes simpler to build, maintain, and configure since it doesn't have to know where it is running. Only that ffwd is available on the loopback interface.

stream-lib - Library for Summarizing Data in Streams
A Java library for summarizing data in streams for which it is infeasible to store all events. More specifically, there are classes for estimating: cardinality (i.e. counting things); set membership; top-k elements and frequency. One particularly useful feature is that cardinality estimators with compatible configurations may be safely merged. These classes may be used directly in a JVM project or with the provided shell scripts and good old Unix IO redirection.

Eventsourced - Akka based Reliable Messaging
A library that adds event-sourcing to Akka actors and can be used for building scalable, reliable and distributed stateful Scala (web) applications. It appends event (or command) messages to a journal before they are processed by an actor and recovers actor state by replaying them. Appending event messages to a journal, instead of persisting actor state directly, allows for actor state persistence at very high transaction rates. Actor state can also be replicated by event-sourcing actor copies on hot-standby slave nodes so that they can start handling new events immediately should a master go down.
