Download e-book for iPad: Mastering Akka by Christian Baxter

Key Features

• This publication might help you remedy anemic types with domain-driven design
• We conceal significant Akka programming innovations corresponding to concurrency, scalability, and reactivity
• You will study recommendations like occasion Sourcing and CQRS through Akka endurance, Akka Streams, Akka Http in addition to Akka Clustering

Book Description

For a programmer, writing multi-threaded functions is important because it is critical to damage huge projects into smaller ones and run them at the same time. Akka is a allotted computing toolkit that makes use of the abstraction of the Actor version, permitting builders to construct right, concurrent, and disbursed purposes utilizing Java and Scala very easily.

The publication starts off with a brief creation that simplifies concurrent programming with actors. We then continue to grasp all facets of domain-driven layout. we will train you the way to scale out with Akka Remoting/Clustering. eventually, we introduce Conductr as a method to install to and deal with microservices throughout a cluster.

What you are going to learn

• Use Akka actors to permit parallel execution
• Build out domain-driven layout dependent elements like entities and aggregates
• Respond to command requests on that mixture root that impact the interior state
• Leverage Akka endurance, protobuf and Cassandra to save lots of the power nation of you entities
• Build out complicated processing graphs with the Graph Builder DSL
• Understand the dynamic push/pull nature of backpressure dealing with inside of Akka Streams
• Route HTTP requests to an actor and go back a response
• Deploy actor circumstances throughout a suite of nodes through Conductr for prime availability

About the Author

Christian Baxter, from an early age, has consistently had an curiosity in realizing how issues labored. growing to be up, he enjoyed demanding situations and loved to tinker with and fasten issues. This inquisitive nature was once the driver that finally led him into desktop programming. whereas his fundamental concentration in university was once existence sciences, he consistently put aside time to review pcs and to discover all features of computing device programming. while he graduated from collage throughout the peak of the net increase, he taught himself the mandatory abilities to get a task as a programmer. he is been fortunately programming ever in view that, operating throughout assorted industries comparable to assurance, go back and forth, recruiting, and advertisements. He loves construction out high-performance allotted platforms utilizing Scala at the Akka platform.

Christian used to be many years Java programmer earlier than making the change over to Scala in 2010. He was once trying to find new applied sciences to construct out excessive throughput and asynchronous platforms and enjoyed what he observed from Scala and Akka. due to the fact then, he is been an important recommend for Akka, getting a number of advert tech businesses he is labored for to undertake it as a method of establishing out reactive purposes. he is additionally been an occasional contributor to the Akka codebase, deciding upon and supporting to mend matters. whilst he isn't hacking away on Scala and Akka, you could frequently locate him answering questions about Stackoverflow as cmbaxter.
