DAS logging DB¶
The DAS logging DB holds information about all requests made to DAS. All records are stored in a capped collection of MongoDB. Capped collections are fixed sized collections that have a very high performance auto-LRU age-out feature (age out is based on insertion order) and maintain insertion order for the objects in the collection.
