What can Lagom do for you?

" summary

Shows concrete features and demos: Lagom sits on Play and Akka Persistence and enforces single-writer via cluster sharding, demonstrates entity passivation, event sourcing + CQRS with a persistent entity API, and a read side using JDBC/Slick read-side with exactly-once offset tracking (offset and DB write in one transaction). Live demo boots Postgres and Kafka, wires ServiceCall APIs to WebSockets and topics, shards tags (example 10 shards) and generates clients — useful if planning Akka-based microservices with built-in persistence and sharding.
