Configuration V1

This section of the YDB documentation describes Configuration V1, the primary way to configure YDB clusters.

Configuration V1 is a two-level YDB cluster configuration system consisting of static configuration and dynamic configuration:

1. Static configuration: a YAML format file that is located locally on each static node and used when starting the ydbd server process. This configuration contains, among other things, static group and State Storage settings.
2. Dynamic configuration: a YAML format file that is an extended version of static configuration. It is loaded via CLI and reliably stored in the Console tablet, which then distributes the configuration to all dynamic cluster nodes. Using dynamic configuration is optional.

You can learn more about Configuration V1 in the Configuration V1 Overview section.
