The JanusGraph FoundationDB Storage Adapter

on YouTube ↗17m

" summary

JanusGraph gets a working FoundationDB storage adapter that maps adjacency-list vertex/edge rows into FoundationDB using the directory layer and tuple encoding, stores values as serialized byte arrays, and inherits distributed ACID so operations that produced "edges to nowhere" on Cassandra now raise a conflict on commit instead of corrupting the graph. Tests are adapted from the BerkeleyDB adapter, current limits include ~5s transaction window, and future work targets Redwood support, ID allocation simplification, collocated query routing, and built-in full‑text indexing.
