Some queries, mostly reporting ones, have to be optimised when they use tables with millions of rows because their execution times make them unusable. We will see how to improve their performance including certain features that are specific for Oracle databases.
As applications grow it is normal to break them down into smaller pieces that are easy to combine and maintain. The challenge comes in the integration between these pieces as an small change in one of them may break the communication with the others, and we may not notice it until we get emails from users. We are going to see how to detect this automatically using contract testing.
One of the challenges of using microservices is the lack of transactions in operations that span multiple services. We will see how to solve it using a standard patten.
One of the challenges of the microservices architectures is that the data is managed by different services what makes difficult to do queries across multiple domains. Let’s see a few approaches and the advantages and drawbacks of each of them.
Organisations cannot work on their own as they have to integrate with customers and suppliers. I will explain some of the integration types I have worked on until now.
There are many debates about which type of database is better. I will focus on how to use them for a specific case and how to evolve the design as needed.
Code quality is usually underrated in some organisations because it is an aspect that customers don’t see and don’t pay for. However it is quite important in both the short and long term. I will expose some of the reasons.
Startups are usually in a rush to deliver features as fast as possible to compete with other companies. However this makes them sometimes go slower and lose customers. Let’s see why it is important to dedicate some time to stabilise the platform.
Startups usually have a big growth after receiving investments. Many people think that the challenge is to find the candidates in a city as competitive as London, but that’s the easy part. I will share what I learned being part of a team that multiplied its size in just a few months
