Driver Registry

dbc installs drivers from a "driver registry" which is an internet-accessible index of installable ADBC driver packages.

By default, dbc is configured to communicate with Columnar's public and private driver registries. Most drivers will be from the public registry but some will be marked with a [private] label which means they're from the private registry. See Private Drivers for information on how to install and use private drivers.

When you run a command like dbc search or dbc install, dbc gets information about the drivers that are available from each configured registry by downloading its index.yaml or using a cached copy.
