Batch processing is an often occuring taks when developing applications. With Spring boot, you can now easily write batch processes using Spring batch. In this tutorial I'll use Spring batch to index markdown documents into Solr.

Indexing documents is quite easy with Apache Solr and Tika. In this tutorial, I'll demonstrate how to configure both and to run them within a Docker container.

Forget REST, get started with GraphQL! In this tutorial I'll be using GrapQL mutations with Spring boot to create a next level API.

Forget REST and learn GraphQL! In this tutorial I'll be using Apollo as my GraphQL client library together with Angular to create even more powerful applications.

Forget REST, start with GraphQL! In this tutorial I'll show you what the benefits are of GraphQL and how you can use GraphQL with Spring boot to create even better APIs.
