Copy documents from one DocumentCollection to another?

Question

In my Azure CosmosDB, that I use with the Gremlin API there is one database called graphdb with several {DocumentCollections}. I would like to copy a selected set of Vertices and Edges from one collection (graphdb) to another (Tintin).

I managed to do this by transferring all data via the client, but it would be much easier if data stayed in Azure. Thus I tried some SQL in the Azure portal like:

SELECT *
INTO Tintin 
FROM graphdb;

However, this seems unsupported.

Answer 1

Now you cannot join multiple collections and you query violates this rule.

But I think +1 for your idea, you should post it on https://feedback.azure.com/
