Managed MySQL Experience At LinkedIn

Submitted Aug 13, 2021

MySQL is used as a primary data store by a majority of internal tools at LinkedIn. We host over 2000 databases of different use-cases. To support our clients better, we have developed a few tools around MySQL. In this talk we will discuss how our tools improved the developer experience while using MySQL.
We will talk about how a database is requested and provisioned by the clients and how they get access to their respective databases the way they want i.e. from having an all-round admin access for complete control to only read-only access for Select queries. We will also throw some light on the Query Analyzer tool that has helped developers identify and fix their slow queries. Lastly, a brief about how the MySQL servers are highly available for the developers, which is achieved by the MySQL Orchestrator . With these tools in action, we provide the developers a managed MySQL experience at LinkedIn.
