Question

I am new to mongoDB. I am working on building an application which requires implementing LRU policy on the collection. In the mongoDB site i see capped collections support FIFO. Is there any other collection which support LRU. Throught the documentation i see only capped collections in the site. Are there any other collections in mongoDb.

Are collections by default capped in mongodb?

Answer 1

MongoDB capped collections are the only kilobyte size-limited collections supported by the database. There is no built-in support for LRU or FIFO based on limiting to a particular number of documents.

Collections are not capped by default in MongoDB – a capped collection is a special case.
