Distributed Data Storage with Data Versioning

Lukas Hejtmanek

In this paper, we are demonstrating the concept of distributed file system that supports file versioning, file sharing, and endless files based on sliding window approach. It is based on distributed storage substrate providing immutable block allocations, and metadata manager, that maps files to data blocks using metadata. While file versioning and read-write sharing is often understood as contradictory, we demonstrate the approach that allows both properties to coexist. We have described the application-level prototype implementation, that we use for verifying this concept.
