CRDTs and Databases: A Hands-On Tutorial

Summary: Explains why conventional isolation and read-write transactions force aborts or lost updates under highly available partition tolerance, motivating CRDTs. Introduces CRDVs, integrating CRDT semantics with relational databases and SQL while retaining query optimization. (summarized by gpt-5.6-luna on Aug 28 2026)
