scala.sys - Interaction with other processes and the operating system; scala.util.matching - Regular expressions; Other packages exist. See the complete list on the right. Additional parts of the standard library are shipped as separate libraries. These include: scala.reflect - Scala's reflection API (scala-reflect.jar Both types make available many of the standard operations found in the Scala collections API. The conversion to ArrayOps is temporary, as all operations defined on ArrayOps return an Array, while the conversion to ArraySeq is permanent as all operations return a ArraySeq. The conversion to ArrayOps takes priority over the conversion to ArraySeq. For instance, consider the following code For building simple, CRUD-style REST APIs in Scala, the Play Framework is a good solution. It has an uncomplicated API that doesn't require us to write too much code. In this tutorial, we're going to build a REST API in Scala with Play. We'll use JSON as the data format and look at multiple HTTP methods and status codes. 2. The Example Projec

The DataFrame API is available in Scala, Java, Python, and R. In Scala and Java, a DataFrame is represented by a Dataset of Rows. In the Scala API, DataFrame is simply a type alias of Dataset[Row]. While, in Java API, users need to use Dataset<Row> to represent a DataFrame Scala began life in 2003, created by Martin Odersky and his research group at EPFL, next to Lake Geneva and the Alps, in Lausanne, Switzerland. Scala has since grown into a mature open source programming language, used by hundreds of thousands of developers, and is developed and maintained by scores of people all over the world A Map is an Iterable consisting of pairs of keys and values (also named mappings or associations ). Scala's Predef object offers an implicit conversion that lets you write key -> value as an alternate syntax for the pair (key, value). For instance Map (x -> 24, y -> 25, z -> 26) means exactly the same as Map ( (x, 24), (y, 25), (z,.

A library for parsing and querying XML data with Apache Spark, for Spark SQL and DataFrames. The structure and test tools are mostly copied from CSV Data Source for Spark. This package supports to process format-free XML files in a distributed way, unlike JSON datasource in Spark restricts in-line JSON format
TL;DR: In this article we're using to use Scala and the Play Framework to build an API that serves blog posts and comments, and then secure the API using access tokens. We will build the API from scratch over the course of this article, but if you'd like to see the final result, you can find the sample code on GitHub.com.. Let's build an API using Scala and the Play Framework Automation in Scala: API tests for gRPC service Posted on June 12, 2021. Photo by Nick Fewings on Unsplash. What is gRPC? gRPC - is a modern Remote Procedure Call framework created and popularized by Google but now is under CNCF license. The main idea of the framework is to provide for clients, written in various languages, a possibility to execute remote calls to the server as if it is a. Returns a new Dataset where each record has been mapped on to the specified type. The method used to map columns depend on the type of U:. When U is a class, fields for the class will be mapped to columns of the same name (case sensitivity is determined by spark.sql.caseSensitive).; When U is a tuple, the columns will be mapped by ordinal (i.e. the first column will be assigned to _1) Scio is a Scala API for Apache Beam and Google Cloud Dataflow inspired by Apache Spark and Scalding. Scio 0.3.0 and future versions depend on Apache Beam ( org.apache.beam) while earlier versions depend on Google Cloud Dataflow SDK ( com.google.cloud.dataflow ). See this page for a list of breaking changes Scala collections systematically distinguish between mutable and immutable collections. A mutable collection can be updated or extended in place. This means you can change, add, or remove elements of a collection as a side effect. Immutable collections, by contrast, never change. You have still operations that simulate additions, removals, or updates, but those operations will in each case.

Scala (/ ˈ s k ɑː l ɑː / SKAH-lah) is a strong statically typed general-purpose programming language which supports both object-oriented programming and functional programming.Designed to be concise, many of Scala's design decisions are aimed to address criticisms of Java. Scala source code can be compiled to Java bytecode and run on a Java virtual machine (JVM) This example is in Scala, but Play also has a Java API which looks and acts just like the Scala API, and has a corresponding play-java-rest-api-example project in the play-samples repo. For instructions on running and using the project, please see the appendix. This project also comes with an integrated Gatling load test - again, instructions are in the appendix.

Scala API Extensions # In order to keep a fair amount of consistency between the Scala and Java APIs, some of the features that allow a high-level of expressiveness in Scala have been left out from the standard APIs for both batch and streaming. If you want to enjoy the full Scala experience you can choose to opt-in to extensions that enhance the Scala API via implicit conversions

An Option[T] can be either Some[T] or None object, which represents a missing value. For instance, the get method of Scala's Map produces Some(value) if a value corresponding to a given key has been found, or None if the given key is not defined in the Map..

The Scala Inference API was designed for ease of use and it offers additional capabilities beyond those discussed in this blog post. Predictor can handle text inputs and outputs, so you can try it. Scala provides so-called partial functions to deal with mixed data-types.

The following article is good. It teaches you about partial functions in a very nice way and explains why case has to be used for.
