<br>
During the provider creation, a lot of SQL requests are made to check a lot of thing even if the use estimated metadata is checked :<br>
* Fields list<br>
* geometry type<br>
* primary key<br>
* extent<br>
* capabilities (read, insert, update, delete)<br>
<br>
You can take a look at these PRs to have an idea on all the SQL request made at the creation :<br>
