Computers are very good at serializing, sequential writing, and sequential reads are highly efficient. In general, we think that reading data from main memory is more than reading chunks from disk, but the actual situationNot necessarily, when we do the main memory random addressing the load is actually higher than the sequential read disk. So what is the inspiration for database optimization based on the c
