Is there an analogue of materialized views in MongoDB?

Question

MongoDB

It is necessary to collect data from several nodes with mongo, execute an aggregating query in them and cache them for a while. In a normal db, I would use dblink and materialized view for this, but what can mongo offer in this regard?

Answer 1

The short answer is no.
Longer - it is possible to fasten Map/Reduce. It has several output options that can be forced to write the data you want to the collection you want. It turns out such a materialized view emulator. Only, of course, with a big, big redundancy.
