WHAT'S NEW IN OPENSEARCH 3.8

Summary from the TLDR Data newsletter

OpenSearch 3.8 improves vector ingestion, radial query throughput, and median query latency while expanding AI-agent support. MCP now works across all agent types, tool discovery is richer, and gRPC streaming inference lowers token latency. Analytics teams also get new PPL/SQL tooling, Grok debugging, one-click Prometheus alerts, and search-relevance workflow improvements.
