We observe that more and more customers are starting to use cloud computing. This is no longer a forbidden fruit, but it is becoming one of the key elements of modern IT infrastructure. Most companies have some combination of cloud and on-premise solutions. The number of applications from different vendors used in large corporations as well as smaller startups are growing rapidly. The second notable trend is the willingness to react quickly, change strategies and generate innovative ideas based on as muc...

Razem z Jakub Gutkowski i Piotrkiem Stappem przygotowaliśmy dokument o tym Jak zacząć pracę z Kubernetes.

In several recent posts, we discussed two ways to trade off correctness for performance in database systems. In particular, I wrote two posts (first one and second one) on the subject of isolation levels, and one post on the subject of consistency le...

A little while ago I blogged here and I set it up to be a "continues..." style post. I haven't had the energy to continue it in that context, and this fact was putting me off concluding the post. I then realised: the thing that matters isn't some overarching narrative structure, but that I get my ideas down. So: I'm aborting any attempt at making this post a continuation, and just focusing on the content! There's been a lot of confusion over when to use Task[

Reading time ~7 minutes I am not a big fan of writing tests. I like having them, but I find writing them to be boring. That said, retesting manually is even more annoying, so I write tests. The thought that there has to be a better way, never passed. I tried a few approaches. After some experimentation, I think I have the answer - DDT (Data Driven Testing) Before we dig into what Data Driven Tests are, let’s look at some standard, non-DDT tests.What we will be testing? There is a fragile line for cod...

I've decided to create a series of blog posts where I will present what I've recently learned about the traps related to the multithreading in C#. I will also show you my proposition of Roslyn analyzers that can possibly help to avoid those issues right at the stage of writing the code. This part is about choosing a suitable object for locking.

Reading time ~4 minutes NoSQL PaaS databases like AWS DynamoDB or Cosmos DB offer incredible capabilities in scale, speed, and availability. There is also a dark side to those databases. They will punish anyone greatly for mistakes. And no mistakes are punished more than choosing the wrong partition key. Below is an ORDERED list on how to approach selecting the partition key.1. Transaction boundary I can’t stress this enough.This is the most critical factor. If our transaction boundary is wrong, pleas...
