In my previous two posts on Scala Compiler options, we saw a number that can improve your experience developing Scala. In this post I want to focus on one option in particular: -Xlint.If you thought the other options made your life better, this one will improve it by leaps and bounds.
Here’s the situation: At Threat Stack we consume a torrent of security event data every day, and as many new customers come on board, the amount of data we need to ingest, transform, store, and retrieve just keeps growing. About a year ago, we implemented a caching layer to allow us to display more aggregated information to customers on our Dashboard, which was powered by ElasticSearch Aggregates.
Scala offers a number of advanced language features that are disabled by default. If you try to use any of them, the compiler will generate a warning informing you of their usage. There are a number of reasons that you might want to enable features (or keep them disabled). In this post, we will explore what each language feature is and under which circumstances you might want to enable them. (For a discussion of basic Scala Compiler options that we find useful at Threat Stack, see Part 1 of this series.)
At Threat Stack we love databases, and as we started to expand our Scala code base, we quickly realized we wanted to standardize on a way to talk to the RDMS within our Scala projects. As we explored the realm, we came across four projects that seemed to have the most potential: ScalikeJDBC, Quill, Jooq, and Doobie. We had already been playing with ScalikeJDBC for awhile, but these other libraries offered interesting features, so we began to investigate.
In this post, we’ll take a look at some of the pros and cons of ScalikeJDBC and Quill. In a followup, we’ll discuss Jooq and Doobie.
At Threat Stack, we like to leverage our tools to the fullest. Since we use Scala, it only makes sense for us to always be looking into ways of getting the most out of the Scala Compiler to enhance our productivity. And, as it turns out, the Scala Compiler offers a number of features that makes our lives way better!
After spending significant time in dynamic languages, learning Scala can be challenging, so having the right tools (like IntelliJ) at your fingertips can make all the difference.
