Hitchhiker-Tree is a functional, immutable, off-heap, snapshottable sorted map data structure (a persistent key-value tree) designed for scalable, high-performance storage in Clojure / ClojureScript systems. It blends ideas from fractal trees and B-trees, supports lazy loading, and can persist incrementally to arbitrary backends. It is used as a backend for systems like Datahike and can support enormous data sets while retaining functional persistence semantics. Outboard is a simple API for your Clojure applications that enables you to make use of tens of gigabytes of local memory, far beyond what the JVM can manage. ...

TreeBASE is a database and web front end that stores phylogenetic trees and the data matrices used to generate them. The current iteration comprises a complete rewrite of the schema and web layer, and will include a web services layer.

Our goal is to create the world's fastest extendable, non-transactional time series database for big data (you know, for kids)! Log file indexing is our initial focus. For example append only ASCII files produced by libraries like Log4J, or containing FIX messages or JSON objects. Occursions was built by a small team sick of creating hacks to remotely copy and/or grep through tons of large log files. We use it to index around a terabyte of new log data per day. You can use it too. Who...
