pgvector vs Apache Airflow
Both are credible choices. The decision comes down to which property your workload actually depends on, and neither vendor pays us to say otherwise.

Side by side
pgvector
Vector search inside Postgres, no separate vector database to operate.
- Strongest at
- one database for relational and vector data, with transactions across both
- Trade-off
- at very large vector volumes a dedicated index outperforms it
- Vendor
- Open source
Apache Airflow
Workflow orchestration for data pipelines, with a mature scheduler and operator ecosystem.
- Strongest at
- a huge operator library and battle-tested scheduling
- Trade-off
- operationally heavy for a handful of simple scheduled jobs
- Vendor
- Open source
How we would actually choose
Choose pgvector when one database for relational and vector data, with transactions across both is the property your workload depends on, and accept that at very large vector volumes a dedicated index outperforms it.
Choose Apache Airflow when a huge operator library and battle-tested scheduling matters more, accepting that operationally heavy for a handful of simple scheduled jobs.
In practice most production systems we build use both, routed by task. Standardising on one option for tidiness usually costs more than the tidiness is worth.
Orqent Labs holds no reseller commission on pgvector or Apache Airflow. We benchmark both on your workload and report what the numbers say.
Questions
pgvector or Apache Airflow, which should we use?
Pick pgvector when one database for relational and vector data, with transactions across both is what your workload depends on. Pick Apache Airflow when a huge operator library and battle-tested scheduling matters more. Most production systems we build end up using both for different tasks rather than standardising on one.
What is the catch with pgvector?
At very large vector volumes a dedicated index outperforms it.
What is the catch with Apache Airflow?
Operationally heavy for a handful of simple scheduled jobs.
Do you have a preference?
Not a fixed one, and we hold no reseller commission on either. We benchmark both on your actual workload and recommend from the result, which occasionally means recommending neither.
