      Description

      In order to prevent cache pressure, background validation should periodically start a new storage transaction at the same read timestamp and then roll back its current storage transaction. This overlap of transactions should prevent WiredTiger from evicting data needed by the transactions, but the establishment of a new snapshot will allow eviction to move newly committed updates into the durable history store.
