Scala vs Python- Which one to choose

Choosing a programming language for Apache Spark may be a subjective matter as a result of the reasons, why a specific data scientist or a data analyst like Python or Scala for Apache Spark, won't continuously be applicable to others. Based on distinctive use cases or a selected reasonably big data application to be developed - data consultants select that language may be a higher fit for Apache Spark programming. It’s helpful for a data scientist to be told Scala, Python, R, and Java for programming in Spark and select the popular language supported the potency of the purposeful solutions to tasks. Allow us to explore some important factors to appear into before picking Scala vs Python because of the main programming language for Apache Spark.

Hadoop’s faster cousin, Apache Spark framework, has Apis for processing and analysis in numerous languages: Java, Scala, and Python. For the aim of this discussion, we are going to eliminate Java from the list of comparison for big data analysis and process, because it is just too long-winded. Java doesn't support Read-Evaluate-Print-Loop (REPL) that may be a major deal breaker once choosing a programming language for big data processing

Scala and Python are both simple to program and facilitate data experts get productive quickly. data scientists typically favor to learn each Scala for Spark and Python for Spark, however, Python is typically the second favorite language for Apache Spark, as Scala was there initially.

Scala vs Python- Performance

Scala programming language is ten times quicker than Python for data analysis and process because of JVM. The performance is mediocre once Python programming code is employed to create calls to Spark libraries however if there's the heap of process concerned than Python code becomes a lot of slower than the Scala equivalent code. Python interpreter has an in-built JIT (Just-In-Time) compiler that is extremely quick however it doesn't offer support for numerous Python C extensions. In such things, the Python interpreter with C extensions for libraries outperforms interpreter.

Using Python against Apache Spark comes as a performance overhead over Scala, however, the importance depends on what you're doing. Scala is quicker than Python once there square measure less variety of cores. Because the variety of cores will increase, the performance advantage of Scala starts to decrease.

Scala vs. Python – Advanced features

Scala programming language has many existential varieties, macros, and simplicity. The arcane syntax of Scala would possibly create it tough to experiment with the advanced options which could be incomprehensible to the developers. However, the advantage of Scala comes with using these powerful options in vital frameworks and libraries.

Having said that, Scala doesn't have enough data science tools and libraries like Python for machine learning and natural language process. Spark MLlib –the machine learning library has solely fewer ml algorithms however they're ideal for big data processing. Scala lacks sensible image and native data transformations. Scala is certainly the simplest choose for Spark Streaming feature because Python Spark streaming support isn't advanced and mature like Scala.

“Scala is quicker and moderately easy to use, whereas Python is slower but very easy to use.”
