## Remote Execution Caching Compiler (RECC) Engineering CppCon 2024 September 19, 2024 Shivam Bairoliya Software Engineer TechAtBloomberg.com © 2024 Bloomberg Finance L.P. All rights reserved. ## ## What is RECC? • Remote Execution Caching Compiler (RECC) Open source build tool that wraps compiler commands and optionally forwards them to a remote build execution service Encompasses the capabilities capabilities of both ccache and distcc ☐ Supports remote linking and caching ## • Designed to share caches across diverse toolchains Works with many compiler toolchains (GCC, Clang, Solaris CC) o Supports

Chapter 6 covers the GitHub hosting version control diagram Furthermore, many of these systems deal pretty well with having several remote repositories they can work with, so you can collaborate with different groups of people in different

This evaluation is known as query planning, and results in a query execution plan. The Execution Plan is dependent on both the query and the associated VSchema. One of the underlying
