Since the lookaside is being replaced by the history store and the cache-usage / cache-pressure behaviour and statistics are not clear at the moment, there is no replacement available to the lookaside score.

Sure, you can assign it to execution to remove the test. I thought this unit test was already disabled? Hasn't the lookaside score been set to a constant 0 with the WT durable history drop, making the CreateAndCheckForCachePressure unit test fail? I don't see any BFG/BF tickets.

dianna.hohensee, I'm wondering what actions the storage engine group can do about this ticket? We don't have a lookaside table going forward and there is currently no equivalent way to measure cache pressure. If this test simply doesn't make sense anymore can I assign this to your team to deal with removing it? (alexander.gorrod thought you might best answer these questions). |
