Airbyte¶
Airbyte is an open-source data-integration platform for moving data between sources (operational databases, SaaS APIs) and destinations (data warehouses, data lakes). It's one of the canonical ETL/ELT integration engines PlanetScale recommends for offloading OLAP workloads from Vitess/ MySQL clusters to a specialised analytical warehouse.
Functionally comparable to Fivetran (proprietary managed service) and Stitch (now part of Talend) — the three are frequently listed interchangeably as integration-engine options for OLTP→OLAP data movement.
Role in the PlanetScale architecture¶
From sources/2026-04-21-planetscale-what-is-htap:
For large ETL workloads, we support and recommend data integration engines such as Airbyte, Fivetran, and Stitch, with which you can offload these processes to other platforms that are more specialized in OLAP workloads.
PlanetScale's explicit architectural recommendation is: PlanetScale handles OLTP; Airbyte (or peer) captures changes and loads them into a specialised warehouse (Snowflake, BigQuery, Redshift, Databricks) for analytical workloads. This maps onto the wiki's CDC driver ecosystem pattern and physical resource isolation principle.
