# Object-store CSV/text/Avro

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.

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

## Names and inspection notes

### 2006–2007: S3 (Hadoop block-backed files)

S3 launched in March 2006. Hadoop’s experimental S3 filesystem was implemented that December and shipped in January 2007. It stored Hadoop file blocks as objects, rather than querying ordinary S3 files directly. The 0.01% slice is an illustrative allowance for early use, not a measured adoption share.

### 2008–2026: Object-store CSV/text/Avro

This category is shown in the storage layer.
