The Spring Data MongoDB Project
summary
Demo of Spring Data MongoDB shows actual code: POJO annotated with @Document, use of MongoTemplate for queries and atomic updates (push/pop, $inc) and auto-generated repositories (findByAuthor). Explains default async driver behavior and how to set per-operation write concerns (journal, w=majority). Live setup builds a three-node replica set, adds shards via mongos and config servers, shows chunk splitting (64MB default) and automatic rebalancing; aggregation, TTL, GridFS and map‑reduce are supported.
