# Other open formats on object storage · storage · 2026

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.

0.04% of the full storage layer.

[Other open formats on object storage](https://history.columnar.tech/technologies/storage/other-open-object.md): historical names and annual shares.

Tabular analytical work on other open file or table formats in object storage, such as Vortex, Lance, Nimble, and BtrBlocks-based representations. The small allocation follows documented Vortex paths in DataFusion (from 2025) and DuckDB (from 2026); no separate share is estimated for each format. Specialized multimodal, vector-search, geospatial, and scientific array/raster work is excluded. Work governed by Iceberg, Delta, Hudi, or DuckLake stays with that table format; internal encodings and caches are not counted again.

## Contributions by compute engine

Each figure is a share of the full storage layer.
