Comparison
Quayen vs Airbyte for MySQL to BigQuery
Airbyte is an open-source data-integration platform with a large connector catalog, available self-hosted or as Airbyte Cloud. Its MySQL source supports CDC, read during scheduled syncs. Quayen streams MySQL changes into BigQuery continuously.
| Quayen | Airbyte | |
|---|---|---|
| How changes move | Continuous: changes land in BigQuery within seconds | Scheduled syncs; CDC changes are read on each sync |
| Pricing model | Monthly active rows; initial copies and re-copies free | Cloud Standard and Plus use credits (database sources use 4 credits per GB synced); Pro and Enterprise Flex are capacity-based |
| Self-hosting | Managed service | Open-source edition you can run yourself |
| Sources | MySQL | Hundreds of connectors |
| Change history in BigQuery | Every change kept in a separate dataset, retention 3 days to forever | Depends on the sync mode chosen (for example append with history, or deduplicated) |
| BigQuery cost controls | Insert-only refreshes, clustered history, refresh interval from 1 min to 1 h | Sync frequency and sync mode |
Choose Airbyte if
- You want an open-source tool you can self-host
- You need many sources beyond MySQL in one platform
Choose Quayen if
- You want changes in BigQuery within seconds, not on a sync schedule
- You prefer per-row pricing to per-GB credits
- You want BigQuery-specific cost optimisation built in
