I am creating a functionality where I need to check if a particular list exist in SharePoint online site/web. The catch here is there would be more than 10000 lists where I am checking. I found a way to check using CSOM code which takes a minute to come back with the result. I am looking for a way which would respond to me faster. I guess REST would have unique URL for the list hence tried that but not able to find any proper information on this. I am looking for suggestions. Any suggestion will be of great help.
Thanks in advance
