Description

In database technology the law of the instrument is a bit overused these days but for a reason! Yelp, like a lot of companies which have been around for a while, has a set of tools we use because we are happy with them. For the Database Engineering team, the tool of choice is MySQL, and it’s a mighty hammer. However, in a fast growing environment it can be difficult to recognize when to scale your data tier and when you might need a screwdriver instead of a hammer, and this has enormous consequences for your application environment. This talk will give you an overview of: * Great reasons to stay solely with MySQL * When and why you should consider adding more tools to the (database) mix. What decision criteria to apply when thinking about this (e.g. Velocity, Volume, Complexity) * Yelp’s choices of alternative databases (Cassandra, Memcached, MongoDB) and how we iterated * The consequences of using other databases, both technological and social * Whether you should follow Yelp into the brave new world of a more well-stocked toolbox and less time hitting your thumb
