Technical Comparison of YugabyteDB with Oracle and PostgreSQL
summary
YugabyteDB claims to deliver Oracle-grade enterprise features by combining a Postgres query layer fork with a distributed storage layer built on RocksDB LSM with SST files, using Raft replication leaders/followers and a hybrid logical-physical timestamp to provide fully ACID, geo‑resilient transactions. Clusters run across AZs (example: three AZs with three nodes each), reads are batched (100,000 rows served with 99 requests ≈ 1,000 rows/request), writes go through buffered protobuf ops and are replicated, and an in‑DB odyssey connection pool reduces client process explosion.
