Hey there! It's time to write a new blog post about something really hot, for example — Kubernetes. In order to make this article even more spicy, I want to talks about Kubernetes in terms of AWS and access to a database. So basically this post is for those of you who wants to setup k8s application on Amazon Cloud and configure access to RDS (Postgres / MySQL) from the application. Let's get started!
I'm working with akka within last ~3 years. I can't say that my knowledge is brilliant. There are still many things which I learn about akka while doing daily programming. Despite this fact, I decided to share my view on actors design and communication techniques. Exactly this talk I made at Scala UA Conference 2018.
An actor model gives us outstanding solution for building of high scale and high load systems. Those of you who work with Akka, know that in the Actor model everything should be represented as an actor. In some sense this axioma simplifies a software development. Is this circumstance as good as it seems? In this article I'm going to demonstrate some approaches which may be applied to actors which need to interact with a database. Just imagine, what sense in a high scale and high load system if it does not communicate with a database?
Hey Scala squad! In this post I'm going to show some ways of extracting values from list or sequence of boxed elements. It's a pretty common case when you have a
Seq[B[A]], but instead of it you need to get
Seq[A]. To be more precise it may be
The question is how to validate a HTTP request body using Akka HTTP directive? Of course we can use for this reason
validate directive, but it has one drawback which I described in my previous post about a model validation in Akka HTTP. You may want to use
require method, but it is not so functional as well. Today I want to show another way for validation of HTTP request body in Akka.
