The document discusses event sourcing and command query responsibility segregation (CQRS) using Akka and Java in a clustered environment. It introduces event sourcing and CQRS, then covers clustering concepts in Akka like distributed actors, clustering, shard distribution, and using Akka persistence and queries for event sourcing and CQRS. The document promotes free resources on these topics and provides contact information for the author.
