Notice before subprocessors change in Data warehouses and databases
A list is a snapshot. Art. 28(2) GDPR gives you a right to object, and that needs advance notice.
1 of 10 vendors we measured here publish it, that is 10%. Last checked 2026-09-02.
10% here against 10% across every category we measure. Data warehouses and databases sits exactly at the overall share for this criterion.

Not measured
We could not look at these, or their robots.txt asks us not to. That says something about our measurement, not about them, and they are left out of the percentage above.
| Vendor | What we found |
|---|---|
| QuestDB | The vendor’s robots.txt excludes us from at least one of these addresses, so this was not measured. |
