It achieves this using ideas from functional programming such as fault tolerance, which works by replaying functional transformation over original datasets. Note: Spark laziness (on transformation) and eagerness (on action) is how Spark optimises network communication using the programming model. map, flatMap.

They created MapReduce and GFS in 2004. Hadoop was hard to program, and Apache Hive came along in 2010 to add SQL. The programming language du jour has changed over the years. At various times it’s been Java, Scala, and Python. In the beginning, there was Google. They published the papers for them in the same year.

Variance in Generics Generics are a fundamental pillar of modern type-safe programming languages. Both Java and Scala support these concepts but implement them differently. In this blog post, well investigate what covariance and contravariance mean, how they are used in generics, and how Java and Scala handle them differently.
