Dynatrace news. We’ve been marketing AI as a key differentiator for nearly five years at Dynatrace. Problem is, these days everyone else is too – making it even harder to figure out if your message is getting through. And, to make matters worse, the technical audience we market to are skeptical of marketing jargon, which means, no matter what us marketers say – they probably won’t believe it anyway.

By having appropriate indexes on your MySQL tables, you can greatly enhance the performance of SELECT queries. But, did you know that adding indexes to your tables in itself is an expensive operation, and may take a long time to complete depending on the size of your tables? During this time, you are also likely to experience a degraded performance of queries as your system resources are busy in index-creation work as well.

The past several years have seen increasing adoption for PostgreSQL. PostgreSQL is an amazing relational database. Feature-wise, it is up there with the best, if not the best. There are many things I love about it – PL/ PG SQL, smart defaults, replication (that actually works out of the box), and an active and vibrant open source community. However, beyond just the features, there are other important aspects of a database that need to be considered.

The ROW_NUMBER window function has numerous practical applications, well beyond just the obvious ranking needs. Most of the time, when you compute row numbers, you need to compute them based on some order, and you provide the desired ordering specification in the function's window order clause. However, there are cases where you need to compute row numbers in no particular order; in other words, based on nondeterministic order.

Furthermore, a principled approach for deriving MRDTs is provided, allowing a wide range of data-types to be lifted to their mergeable, replicated counterparts with

Mergeable replicated data types – part II Kaki et al., OOPLSA ’19.
