# Amazon Athena vendor-specific interface · access · 2020

Revision 1 (11 October 2026) · Modeled snapshot · through 8 October 2026.

All figures are research-informed estimates of analytical activity. Significant errors may remain; decimal places do not imply measurement precision.

0.61% of the full access layer.

[Amazon Athena vendor-specific interface](https://history.columnar.tech/technologies/access/vendor-athena.md): historical names and annual shares.

AWS-managed SQL query service. Its workloads are counted here once, separately from Presto and Trino. Federated native covers work against other databases’ native relational tables; S3 files and open tables keep their own storage categories.

Connections below describe the whole Amazon Athena engine. Access and storage mixes are estimated separately; they are not a joint interface-to-storage distribution.
