Cassandra Wannabe

What?

Distributed data store experiment for MovieLens ratings dataset. Schema is hard-coded to focus on other areas.

Core Goals

• Consistent hashing
• At most 1-hop routing
• Data replication on 2 nodes with Cassandra's SimpleStrategy
• Expose REST api for upsert/read/delete
• gRPC CRUD service for the nodes
• Observability with OpenCensus.io, exporting to Prometheus and OpenZipkin

Stretch Goals

• Basic implementation of Gossip protocol with UDP packets
• Data streaming to new nodes when cluster grows
• Virtual nodes instead of real nodes
• Memtable that flushes to disk when full
