All figures are research-informed estimates of analytical activity. Significant errors may remain; decimal places do not imply measurement precision.

Layer: storage. Values cover the years in which this category appears in the public timeline. Absence is not proof of zero use.

### 2025–2026: Other open formats on object storage

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.
