N2 - In this paper, we present some insights from the analysis of the drawbacks of the advanced concurrency control techniques. Based on the analysis, we reveal that a commonly used technique for index structures, read-copy update (RCU), has the most significant impact on the throughput and latency of in-memory database systems. For overcoming the drawbacks, we developed Glasstree, a new index structure that produces a smaller load on the memory allocator by enhancing Masstree. Glasstree achieved high throughput and stable latency than Masstree under various workloads.
