This project is my Advanced Database Final Project when I study at NTHU. In this system, I'm using two different databases to handle different workloads. Furthermore, to perform requests properly, I also use the streaming system to decompose the system into distributed.

I choose these software as my infrastructure...

• Container Orchestration - kubernetes: Google level container orchestration also battle proof
• Main OLTP - Cockroachdb: Similar concept as Google Spanner
• Graph Database - Dgraph: GraphQL native database for Geo-Search and FullText-Search
• Streaming - NATS: CNCF's streaming system written in Go which is my most familiar language

There are 4 demo services in this repo. If you want to try this concept make sure you install all the infrasturctures.

• cmd/client: Demo client request by using gRPC client
• cmd/stream: Frontend of all storage service, just a simple publish layer.
• cmd/txn: Handle transaction workload, also use work steal concept.
• cmd/graph: Handle graph workload, also use work steal concept.
