Shlomi Noach, Senior Infrastructure Engineer at GitHub, introduces GitHub's latest open source release: gh-ost, a schema migration solution for MySQL. gh-ost changes the online migration paradigm and overcomes today's limitations and difficulties in MySQL table migrations. gh-ost was designed with performance and operations in mind. It is triggerless, controllable, auditable, suspendable, and testable. Shlomi will discuss the reasoning for embarking on developing a new solution, the existing MySQL migrations landscape, gh-ost's underlying logic, operational perks, future plans and surprising implications. Shlomi will also share thoughts on the open source landscape and the role he expects gh-ost to play.
