# TiDB 2.1.7 Kyle Kingsbury 2019-06-12 TiDB is a distributed, auto-sharded SQL database based on Google's Percolator model. Despite promising snapshot isolation, TiDB 2.1.7 through 3.0.0-beta.1-40 thanks to two auto-retry mechanisms which blindly re-applied updates when a transaction conflicted. TiDB also supports a select ... for update statement which mostly, but not entirely, prevents write skew disabled, TiDB 2.1.8 through 3.0.0-beta.1-40 passed our tests for snapshot isolation and single-key linearizability. 3.0.0-rc.2, which disables auto-retry by default, also passes. Finally, TiDB has a theoretical

overview of what the poster reports on. Title: Pipeline architectures in C++: overloaded pipe operator | std::expected and its monadic operations ## Brief overview: Functional programming in C++ is the overloaded pipe operator. In this poster I show how to implement a custom pipeline framework that employs std::expected, available since C++23. An overloaded custom pipe operator will be presented, my book about C++ [1][3]. One of the topics was to describe the behavior of the overloaded pipe operator | in std::ranges. I came across Ankur's Satle lecture [4] and decided to expand on this topic
