问题 Is MongoDB capable of funding number of random documents without making multiple queries? e.g. I implemented on the JS side after loading all the document in the collection, which is wasteful - hence just wanted to check if this can be done better with one db query? The path I took on the JS side: get all data make an array of the IDs shuffle array of IDs (random order) splice the array to the number of document required create a list of document by selecting them by ID which we have left
