Is there a way to "touch" a document in ArangoDb

Question

I need to be able to "touch" a document (for optimistic purposes) in ArangoDb in order to check and update the _rev without modifying any other data in the document. I have yet to find a way to do this generically with AQL or Javascript Driver without knowing something about existing data in the document. What am I missing?

Answer 1

Some research and testing points to using AQL like:

LET doc = DOCUMENT(@id)
REPLACE doc IN @@collection OPTIONS { ignoreRevs: false, revision: @revision }
