Question

I need retrieve all RavenDB collection names present into a database. Is there any way to do this? How?

Answer 1

If you’ve used the studio at all, you’ll see it created an index called Raven/DocumentsByEntityName. If you don’t use the studio, or you want to ensure it’s there, you can build it yourself with:

documentStore.ExecuteIndex(new RavenDocumentsByEntityName());

The way that Raven Studio builds it’s “collections” list is by getting the terms of the Tag field from this index. You can do the same thing:

var results = documentStore.DatabaseCommands
                           .GetTerms("Raven/DocumentsByEntityName", "Tag", "", 1024);

(If you expect more than 1024 different entity types for some reason, then paginate.)
