SBE will replan if the cached plan uses more works than the 'decisionReads'. See here. The classic engine only replans when the cached plan usesĀ ~10x more works than expected. See here.
This could lead to scenarios where the query system repeatedly evicts cached plans when it isn't really necessary.
