What is Min Key?
MinKey is a special value in MongoDB that represents the lowest possible value for a field. It is considered to be less than all other values in the database. This makes MinKey useful in queries and sorting operations where you want to establish a lower bound. For instance, when searching for documents with a field that is greater than a certain value, you can use MinKey to ensure that all documents are included, as it effectively acts as the smallest possible value.
