    Topic 1:

    TiDB 悲观事务的设计与实现


    Speaker :

    赵磊,TiKV 研发工程师。


    Content : 

    TiDB 一直使用的是 Percolator 乐观事务模型,在 3.0 版本中初步实现了悲观事务模型,本次分享讲介绍悲观事务的设计与实现原理。


    Topic 2:

    Introduction to performance engineering


    Speaker :

    Nick Cameron,PingCAP Senior Database Engineer,Rust core team


    Content : 

    Computer hardware and compilers have evolved hugely, which means that many of the guidelines for writing performant code are now obsolete. 'Big O' complexity (a key tool in understanding performance) is often misunderstood - advances in CPU design have changed performance parameters beyond recognition. The range of available tools and techniques can be overwhelming.

    By better understanding modern computer architecture, you will learn which code and data structures work well, and why some 'fast' code doesn't improve performance at all. You will learn practical strategies for optimisation, specific ways to write faster code, how and what to measure, and how to make better performance-oriented decisions when programming.

    This talk is for intermediate-level developers. You should have a good understanding of general programming, but don't need any background in performance or optimization. Most of the talk will focus on general issues, with some focus on Rust-specifics (but you should get plenty out of it if you don't know or use Rust).
