Introduction to YugabyteDB – Design and Architecture

on YouTube ↗27m

" summary

YugabyteDB claims ACID transactions with cloud native horizontal scaling by adding nodes, showing a concrete replication factor three example across four nodes and automatic re-replication after failures. It uses Raft consensus per tablet, a two‑phase commit for distributed transactions, and a DocDB storage layer built on RocksDB optimized for SSDs. Two APIs exist: YSQL (Postgres-compatible) with snapshot and serializable isolation, and YCQL for Cassandra‑style workloads.
