Show HN: SirixDB – Storing and Querying of Temporal Data (Java and Open Source)

I'm developing a storage system for versioning data at the subfile level, especially well suited for SSDs due to its log-structured COW nature. It implements a novel versioning algorithm called sliding snapshot, a diff-algorithm which makes use of our stable record-identifiers and optionally hashes, another diff algorithm for importing similar XML-documents as a versioned resource as well as novel XPath axis to navigate not only in space, but also in time. Recently, I've implemented a higher level, asynchronous REST-API with Kotlin (Coroutines) and Vert.x in a seperate module.

The system is heavily inspired by the filesystem ZFS.

My goal is to put forth the idea of a versioned, distributed storage system to easily support temporal analytical tasks, which are best applied to a series of revisions in order to analyse how the data has changes. Other tasks might simply include easy undo/redo operations.
