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.

2.4775% of the full storage layer.

[Federated relational native stores (vendor unallocated)](https://history.columnar.tech/technologies/storage/remote-relational.md): historical names and annual shares.

These are the coordinating engines. The source database vendors have not been allocated.

## Contributions by compute engine

Each figure is a share of the full storage layer.
