This post talks about how we make use of Boost.Geometry in MySQL to implement reliable and efficient GIS functionality, as well as changes to the GIS features in the lab release. Now that InnoDB is the default storage engine for MySQL, our user base is rapidly transitioning to InnoDB. One capability that they have been demanding is a performant and scalable GIS implementation. Along with adding R-tree index support to InnoDB, we also decided to replace the original GIS algorithms with a more powerful, reliable, effective and efficient geometric engine.
