How is the instance table meant to be used?

[paulwongx]

In term of the instance table, how is it meant to be used? Supbase mentions it as a table used to "manage users across multiple sites". What is an example of raw_base_config?

Is this table used to store each website OR each website user so raw_base_config would have something like ${website_url}:${user_id}?

The schema for instances is below:

create table
  auth.instances (
    id uuid not null,
    uuid uuid null,
    raw_base_config text null,
    created_at timestamp with time zone null,
    updated_at timestamp with time zone null,
    constraint instances_pkey primary key (id)
  ) tablespace pg_default;
