Sailthru has been using MongoDB in production since 2009, before autosharding existed. For years, we sharded much of our infrastructure using in-app sharding logic. We recently moved to autosharding of our 600 million user profiles. Ian White, Sailthru CTO and Co-Founder, walks through how that decision took place, the strengths and weaknesses of the different sharding approaches, and the details of the migration plan to autosharding.
