An alerting application is used to notify users when new content is available that matches a predefined (and usually stored) query. MarkLogic Server includes several infrastructure components that you can use to create alerting applications that have very flexible features and perform and scale to very large numbers of stored queries.

I am not sure how commits on multiple documents work in RethinkDB, but MarkLogic the reverse query will be executed only after the commit (multiple or single-doc) will have happened (since MarkLogic is ACID).
Another system that supports similar thing is EllasticSearch with query percolation feature
