No more allocation delays: Decoupling snapshots from shard relocation in stateless Elasticsearch
Clusters scale out under load without waiting for a snapshot to finish, because snapshots now read straight from the object store and no longer pin shards in place.
Avoiding and Correcting Hotspots: How Elasticsearch Serverless Balances Shards
Elasticsearch Serverless replaces the Elasticsearch node-weight based shard rebalancing algorithm with resource usage aware rebalancing that avoids index shard colocation, OOM events and write load hotspotting
Your AI agent doesn't need your API key: OAuth 2.1 for Elasticsearch MCP server authentication
OAuth 2.1 lets you connect AI agents to the Elasticsearch MCP server with a browser sign-in instead of an API key. Your agent gets a short-lived token tied to your permissions that you can revoke any time.
17% faster search, zero config: auto-calibrating vector quantization in Elasticsearch
Automatic calibration at merge time picks vector quantization parameters for each segment by predicting recall from a small sample. Here's how we built it into Elasticsearch's merge path.
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 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.
Elasticsearch reindex now relocates across nodes automatically: zero user intervention, no lost progress
Elasticsearch reindex now survives node shutdowns, uses Point in Time for more efficient source iteration, and ships with dedicated management APIs. Reindex-from-remote is GA in Serverless.
One query, multiple Elasticsearch Serverless projects: introducing cross-project search
Cross-project search in Elastic Cloud Serverless lets you query data across isolated projects in a single Elasticsearch or ES|QL request: no duplication, no network peering, and no egress costs from copying logs.
Faster cross-project search in Elasticsearch Serverless with project tags and routing
Scope cross-project search in Elasticsearch Serverless with project routing to skip non-matching projects entirely, or with project tag fields to filter, aggregate, and sort by tag inside the query.
How cross-project search (CPS) works in Elasticsearch Serverless
Elastic Cloud Serverless cross-project search (CPS) treats index expressions as cross-project by default. This post explains how TransportSearchAction scopes projects, resolves index expressions, skips projects with no matches, and validates index resolution against allow_no_indices and ignore_unavailable.
Introducing unified API keys for Elastic Cloud Serverless and Elasticsearch
Learn how Elastic unified control plane and data plane authentication in Serverless with a globally distributed IAM architecture. Use one API key for Cloud and Elasticsearch APIs.
