Opening and closing a database connection every time new transactions take place becomes a bottleneck really quickly. Typically, opening a database connection is an expensive operation. This is mostly because of the associated TCP handshake that's required to create socket connections on both sides. The overhead is even more expensive if the database is hosted on a remote server, which is usually the case. If we could reuse the connection for every subsequent request that gets sent to our database, we might reduce the latency a great deal. An efficient way to mitigate this overhead is to employ database connection pooling. When a process needs a new connection, it is given an existing connection from the pool of connections. When the process has completed the required operation with the database, this connection handle goes back to the pool to...

Overview of this book
Rust is an empowering language that provides a rare combination of safety, speed, and zero-cost abstractions. Mastering Rust – Second Edition is filled with clear and simple explanations of the language features along with real-world examples, showing you how you can build robust, scalable, and reliable programs.
This second edition of the book improves upon the previous one and touches on all aspects that make Rust a great language. We have included the features from latest Rust 2018 edition such as the new module system, the smarter compiler, helpful error messages, and the stable procedural macros. You’ll learn how Rust can be used for systems programming, network programming, and even on the web. You’ll also learn techniques such as writing memory-safe code, building idiomatic Rust libraries, writing efficient asynchronous networking code, and advanced macros. The book contains a mix of theory and hands-on tasks so you acquire the skills as well as the knowledge, and it also provides exercises to hammer the concepts in.
After reading this book, you will be able to implement Rust for your enterprise projects, write better tests and documentation, design for performance, and write idiomatic Rust code.
