# PrestoSQL 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.

0.365% of the full access layer.

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

The PrestoSQL lineage, later renamed Trino, including independently operated and commercial distributions. Athena is excluded from this share and has its own box, despite the shared engine lineage. PrestoDB is also counted separately.

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