# Teradata · compute · 2024

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.

3.2% of the full compute layer.

[Teradata](https://history.columnar.tech/technologies/compute/teradata.md): historical names and annual shares.

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