Ilya Kokorin HTAP Workloads: Challenges and Solutions

— In this talk, we consider challenges posed to modern DMBS by so-called HTAP workloads. HTAP (Hybrid Transactional & Analytical Processing) combines: 1. Fast OLTP-style requests that should be executed with maximal throughput and reasonably low latency. 2. OLAP-style analytical queries that require reading a lot of rows to be executed. As a solution to this question, we consider several approaches: persistent-parallel trees, fork COW approach (from HyPer), MVCC, and HTAP-aware LSM tree (from LASER). Download slides:
