Please watch Percona’s Principal Support Engineer Marcos Albe as he presents “Beyond Relational Databases: A Look Into MongoDB, Redis, and ClickHouse”.

We all use and love relational databases... until we use them for purposes for which they are not a good fit. Queues, caches, catalogs, unstructured data, counters, and many other use cases could be solved with relational databases, but are better solved with other alternatives.

In this talk, we'll review the goals, pros and cons, and good and bad use cases of these alternative paradigms by looking at some modern open source implementations.

By the end of this talk, the audience will have learned the basics of three database paradigms (document, key-value, and columnar store) and will know when it's appropriate to opt for one of these or when to favor relational databases and avoid falling into buzzword temptations.
