Making HTAP Real with TiFlash — A TiDB Native Columnar Extension

From the very beginning, TiDB was designed with the combination of Hybrid Transactional and Analytical Processing (HTAP) workloads in mind. However, since TiKV stores data in a row-oriented fashion, you may have been left wondering how well suited that is for analytics?

In this talk, I will introduce TiFlash which is a native extension of TiDB that offers column-oriented storage to speed up heavy-duty OLAP queries. I will then go over the architecture and some of the design decisions, and how you will be able to use it for your next generation data processing needs.
