How Elasticsearch cut metrics storage by 41% by dropping sequence numbers after replication
Find out how Elasticsearch trims sequence numbers at merge time to cut TSDS storage by 41%, what you give up, and why it's safe for metrics workloads.
Replica management: Inside the system that keeps Elasticsearch Serverless searches fast at scale
A technical walkthrough of how two replica systems (one for failover, one for load balancing) combine every five minutes into a single cache-aware recommendation per index in Elasticsearch Serverless.
Your AI agent reads the fine print: building a RAG pipeline over EU regulations with Elasticsearch and OGX
Learn how to configure Elasticsearch as an OGX vector store, ingest EU regulation PDFs and build a Python RAG agent that runs hybrid BM25 and vector search with source-level citations.
Best practices for building a modern app with vector search
Exploring six vector search tips for building modern AI search applications entirely on Elasticsearch, with an opinionated rationale at each architectural decision.
Elasticsearch simdvec deep-dive: Walking the memory tightrope to 2x better vector throughput
A deep dive into four optimizations (cascade unrolling, batch prefetching, dim-axis unrolling, a structural refactor) that pushed Elasticsearch simdvec to 2x vector throughput by working with the CPU, not against it.
Your Elastic agent, Google's ADK, and zero custom APIs: building “Lucky Planet” over A2A
Elastic Agent Builder's native A2A endpoint lets Google's ADK orchestrate a remote agent, with no custom REST API. Watch it work in 'Lucky Planet,' a random-exoplanet game built end-to-end.
