Ilya Kokorin HTAP Workloads: Challenges and Solutions
In this talk, we consider challenges posed to modern DMBS by socalled HTAP workloads. HTAP (Hybrid Transactional Analytical Processing) combines: 1. Fast OLTPstyle requests that should be executed with maximal throughput and reasonably low latency. 2. OLAPstyle analytical queries that require reading a lot of rows to be executed. As a solution to this question, we consider several approaches: persistentparallel trees, fork+COW approach (from HyPer), MVCC, and HTAPaware LSM tree (from LASER). Download slides:
