Mastering Java Persistence: Best Practices for Cloud-Native & Modernization
summary
Covers concrete strategies: use Redis for caching, sessions and Pub/Sub; MongoDB for embedded documents and avoid retrieving multi‑GB documents; Cassandra for wide‑column denormalized models, Cassandra TTL for expiring data and avoid excessive secondary indexes to prevent slow queries; Neo4j for relationship traversal and recommendations. Presents Java patterns (JDBC, Data Mapper, DAO, Active Record, Repository) and warns tradeoffs; cites a Brazilian VIP‑card case where data-driven offers launch a winery that tops Latin‑America sales for three months.
