| Feature | Scalability Limit | |---------|-------------------| | Max cluster size | Up to 1,000 nodes | | Data capacity per cluster | Petabytes (PB) | | Ingestion rate | > 200 MB/sec per node (streaming + batch) | | Query concurrency | Hundreds of concurrent queries | | Query latency (hot cache) | < 1 second on billions of rows | | Data retention | Unlimited (via cold storage + continuous export) |

This separation allows independent scaling: you can increase compute without moving data.
