Every website wants to become successful. Few websites however undertake the basic and fundamental steps to build a rock solid foundation to ensure a scalable
Software developers love tools for coding, debugging, testing, and configuration management. The more these tools improve the How of coding, the more we see that we're behind the curve on improving the What, Why, and When. If you've been on a project that seemed vague, adrift, and endless, this talk can help. Make your projects run SMART.
Multi Source Replication With MySQL 5.7 @ VerisureKenny Gryp
Verisure, Europe's most popular home alarm with more than 1.8 million customers using the system every day, relies on MySQL for a lot of its customers' data.
Data is stored into a sharded database architecture using MySQL. Some of that data is is being replicated into a centralized data warehouse for business intelligence purposes.
For a long time, Tungsten Replicator has been used to fan-in the data into a single MySQL instance.
This worked well until Verisure expanded. The data growth has increased dramatically ever since, and the architecture began to be difficult to operate.
MySQL 5.7 comes with multi-source replication support out of the box, and as this can simplify the architecture a lot, Verisure became early adopters of MySQL 5.7.
This talk is about being an early MySQL 5.7 adopter. We'll talk about why we did it, how we put it into production, what problems we ran into and what successes we had with MySQL 5.7.
Just about anyone can write a basic SQL query for a table. Not everyone can write a good query though - that takes practice and knowing how to understand what the optimizer is doing with the query. Learn the basics of query optimization so you keep your application engaging the user rather then showing the progress bar as they wait on the database.
A tutorial on MySQL High Availability on the Pacemaker stack. Covers both MySQL on DRBD, and MySQL with MySQL replication.
