The fastest of these databases is Scuba, which achieves subsecond query response time by storing all of its data in memory across hundreds of servers. We are continually improving the code for Scuba and would like to push new software releases at least once a week. However, restarting a Scuba machine clears its memory. Recovering all of its data from disk --- about 120 GB per machine --- takes 2.5… CONTINUE READING
