No DB: Use a Search Engine!
summary
The talk argues for using a search engine (ElasticSearch) as the primary persistence layer instead of a traditional database, demonstrating how ElasticSearch provides scalable storage, replication, snapshotting and a dynamic presentation layer via Kibana. It covers trade-offs—no built-in transactions—and shows how Event Sourcing ideas can address that, with a real production example from an energy-startup handling payment flows.
