Recent work has shown that, despite being aggressively optimized for modern hardware, in-memory online transaction processing (OLTP) systems severely underutilize their core micro-architecture resources [25]. Online analytical processing (OLAP) workloads, on the other hand, exhibit a completely different computing pattern. OLAP workloads are read-only, bandwidth-intensive and include various data access patterns including both sequential and random data accesses.
