      Description

      Devise tests for behavior of the system when timestamped writes continue to happen while the oldest_timestamp ceases to be updated. This situation can happen when a majority of secondaries stop replicating in a replica set.
      Expectation is that as the cache fills with dirty data, the system degrades smoothly and lookaside table usage increases.
