When did twitter start using Scala?

Circa 2009, Twitter’s scalability issues with its Ruby on Rails platform prompted a migration to a Scala-based stack. Today, Twitter is one of the largest organizations using Scala as its main programming language to power its platform.

What is Twitter’s backend written in?

Scala
Right now Twitter’s service is a hybrid of programming languages, Payne says. The user interface runs on Ruby on Rails, which is “fine for people clicking around Web pages,” he says. But by the end of the year, Twitter hopes to have a set of services in the back end that are written entirely in Scala.

What are the major advantages of Scala language?

Scala’s complex features promote better coding and offer a performance increase. Functions, macros, and tuples are just a few of the advancements Scala offers. Scala incorporates functional programming and object-oriented programming into a powerful language.

How does Twitter use Scala?

Twitter needed caching layers and a language capable of handling heavy processes. It was chosen as a fast, advanced, and flexible language, winning over all others. A big factor was the fact that Scala takes from other Java libraries and the company could easily hire a Java developer and switch them over to Scala.

How is Scala better than Java?

According to some other websites as well, Scala is faster than Java. Some programmers even claim that Scala is 20\% faster than Java. But Scala compiler supports an optimization technique called tail call recursion. The optimization makes the Scala code compile faster than Java code.

Why did Twitter move from Ruby to Scala?

A fascinating discussion of why Twitter moved to the Java JVM for their server infrastructure (long lived processes) and why they moved to Scala to program against it (high level language, static typing, functional). Ruby is used on the front-end but wasn’t performant or reliable enough for the back-end.

Why does Twitter use Lambda instead of Scala?

The argument was that scala introduces a big learning curve for new developers. Because of its complicated language features it can become hard to read. So at Twitter they are trying to not overuse the complexities of the language, so the main benefit they get from it are lambdas. Which is now b

What is Scala and why should you learn it?

Scala makes the process of coding itself easier with the variety of integrated development environments you can use. Some of these are good for big projects with sprawling scopes while some are a solid fit for quick patching and coding. Either way, the ability to code through IDEs is a big bonus for long-term work in startups and companies.

Why use Scala for big data analytics?

Perhaps that is why a lot of data analytics software offers support for Scala, making it easy to integrate the software into your system. It’s one of the standout features of Scala because something like Ruby, which Twitter used before transition to Scala, doesn’t have the ability to support big data effectively.
