Analytics

Columnar collects basic, anonymized information in order to help us better understand how dbc is being used.

What data do we collect?

When you use dbc to search for or install a driver, dbc sends requests to the driver registries it's configured to use. By default, these are:

  • The public ADBC driver registry (https://dbc-cdn.columnar.tech), which is affiliated with the ADBC Driver Foundry and hosted by Columnar
  • Columnar's private driver registry (https://dbc-cdn-private.columnar.tech)

Both registries are served from a CDN that Columnar operates on Amazon Web Services. Requests to the CDN include information such as:

  • IP address
  • dbc version
  • Operating system name and architecture (e.g., linux/amd64)
  • A non-reversible but stable per-machine ID and a random UUID (generated once per install)

Tools that access the registries without dbc are asked to set a user agent that identifies them. See the FAQ.

Where does it get stored?

The above data is stored as part of the normal recording of HTTP request logs to the CDN. Logs are stored in a private S3 bucket which is only accessible to authorized Columnar staff.

How long do we collect it for?

Logs are currently not deleted but we plan to set up automatic log pruning and will update this section when we do that.

How do I opt out?

There's currently no mechanism to opt out of this data collection. If you have any questions or concerns, please reach out to us at privacy@columnar.tech.
