# Default Limits

Limits are defined per meter and scale linearly with the number of meters.

| Feature                          | Limit / Description                    | Comments                                                                                            |
| -------------------------------- | -------------------------------------- | --------------------------------------------------------------------------------------------------- |
| Meter events ingestion           | 1M events per hour per meter           | Standard ingestion rate per meter                                                                   |
| Meter events ingestion (roll-up) | 100M events per hour per meter         | Roll-up meters aggregate events into hourly intervals (e.g., sum), increasing ingestion throughput. |
| Usage query rows                 | 100K rows per query (\~6MB limit)      |                                                                                                     |
| Event cancellation               | 1 batch (up to 250 rules) per 12 hours | Batch operation for filtering events                                                                |
| Backfills                        | Up to 60 days                          | Historical data ingestion supported                                                                 |

# Tuning Guardrails

Amberflo is built with cloud-first scalability principles. These limits represent default guardrails to ensure consistent performance and reliability, and are not hard caps and can be increased by provisioning additional compute and memory. 



For higher limits or workload-specific tuning, contact Amberflo support.
