Stateless: Data safety in a stateless world
We discuss the data durability guarantees in stateless including how we fence new writes and deletes with a safety check which prevents stale nodes from acknowledging new writes or deletes
How we optimized refresh costs in Elasticsearch Serverless
We explore how serverless Elasticsearch facilitates searches using data stored in a blob store while maintaining the same visibility semantics as stateful Elasticsearch. We discuss the challenges encountered during implementation and share strategies for balancing costs and complexity.
