Events events events — Anton Davydov on Event Sourcing in Ruby

Anton Davydov's wroclove.rb 2019 talk introducing event sourcing: storing immutable events as source of truth, replaying them into projections, using streams and snapshots, and integrating with Ruby via Ruby Event Store and his own hanami-events gem. Covers trade-offs, data evolution, sagas, CQRS, DDD, and fielded Q&A on GDPR erasure, searching, and cost.
