PersistIT [B+ Tree]

PersistIT: A fast, transactional, Java B+Tree library

From the webpage:

Akiban PersistIT is a key/value data storage library written in Java™. Key features include:

  • Support for highly concurrent transaction processing with multi-version concurrency control
  • Optimized serialization and deserialization mechanism for Java primitives and objects
  • Multi-segment keys to enable a natural logical key hierarchy
  • Support for long records
  • Implementation of a persistent SortedMap
  • Extensive management capability including command-line and GUI tools

For more information

I mention this primarily because of the multi-segment keys, which I suspect could be useful for type hierarchies.

Possibly other uses as well but that is the first one that came to mind.
