In the world of technology, exceptions are said to be as old as programming itself. The occurrence of an exception during the execution of code can result in unexpected behavior unless the exception is properly handled in the code. Exceptions are not bad but are a fundamental part of modern programming. Rather than having a fear of exceptions, it is important to know how to tackle which exception at what moment of time.

Here's how it works and how you can use this functionality with Anypoint MQ. How Does Circuit Breaker Design Pattern Work?

A colleague recently said to me, after expressing a preference to force an empty string instead of allowing NULL: "I don't like dealing with nulls in code.".

This is my first (I hope) post about something no so usual in our regular posts about technology. Usually we discuss new features, talk about how to do something but even for me, a Percona developer, sometimes it is hard to know where and what to touch in PMM.

Dynatrace news. There’s no lack of metrics, logs, traces, or events when monitoring your Kubernetes (K8s) workloads. But there is a lack of time for DevOps , SRE , and developers to analyze all this data to identify whether there’s a user impacting problem and if so – what the root cause is to fix it fast. At Dynatrace we’re lucky to have Dynatrace monitor our workloads running on K8s.
