- Streaming updates: Ingest and update documents continuously for near real time freshness in search results
- Low latency serving: Designed for fast query serving at scale with predictable performance under load
- Deployment flexibility: Run as a self managed service so teams control compute sizing and operational policies
- Natural language to SQL: Ask questions in plain language and get generated SQL you can inspect run and troubleshoot for trust
- Text to chart: Generate charts from questions so non technical users can explore trends without building dashboards manually
- Semantic modeling layer: Define business concepts and metrics so queries map to correct tables with far less ambiguity in production
- Database connectivity: Connect your own databases so answers come from governed data instead of public web content at work
- Governance controls: Use projects members and access rules to keep models and datasets scoped for teams and environments
