0.08% of the full access layer.

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

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