Reading Time: 4 minutes In java-8 streams are introduced to handle huge data so we can process the data efficiently. Streams are lazy and its do not process elements until a terminal condition is reached. After a terminal condition is met then each element is processed individually. If there is a short-circuiting operation at the end, the stream processing will terminate whenever all the conditions are satisfied. The new Continue Reading
Reading Time: 3 minutes First of all, Java 8 Streams should not be confuses with Java I/O streams. The Stream API is use to process collections of objects. Java provides a new additional package in Java 8 called java.util.stream. In stream one or more operations can be perform. The Streams operations are either intermediate or terminal. Stream provides following features: The stream does not store elements. A stream is not Continue Reading
Reading Time: 4 minutes Overview In this blog, we’ll be understand about akka streams and its components. Also, we’ll do a simple exercise that involves each of these components. Introduction Stream A stream is a flow of data that involves moving and transforming data. An element is the processing unit of the stream. Akka Streams In software development, there can be cases where we need to handle the potentially Continue Reading
Reading Time: 3 minutes In this blog, we will learn about the java 8 features and why java 8 is so much popular. After java 8 Java has started supporting the functional style of programming with its Java 8 release. The basic idea of why java enables functional programming is concise the code, less complex, easy to understand, and easy to testing compare to legacy coding styles. Here are Continue Reading
Reading Time: 3 minutes Hi friends in this blog we are going to cover streams, parallel streams and some of the popular function associated with them with example. Introduction Streams are wrappers around data source, which make data processing in bulk easier and fast. A stream is not a data structure i.e. it does not store data. Stream is defined in java.util.stream package. Different ways to create Streams 1) Continue Reading
Reading Time: 3 minutes Hi folks, In this blog we would talk about one of the features of Java 8 which is Streams. The java package java.util.stream contains classes to support functional-style operations on streams i.e. map, filter etc. Streams is not a data structure that stores something instead of it a way to flow data from source to destination with some intermediate operation in between. Let’s take an Continue Reading
Reading Time: 3 minutes Hi guys, with release of Java 8 we get new features like lambda functions, streams etc. and in this blog we are going to have an overview of Streams.Streams reduces the effort for using and accessing the elements in any Collection. So here we will see what are different types of operation in Streams and when to use them. Streams Definition Streams are used when Continue Reading
Reading Time: 4 minutes As the world is growing, so is the data. And analysis of this data has become important. But how will you do it? How will you work with the data whose size is unknown to you? A solution to this scenario is Akka-Streams and here I’m going to discuss it. In this blog you will get to know the basics of Akka-Streams just to get Continue Reading
Reading Time: 3 minutes Java Stream API was one of the major features released with Java 8, that let you code in declarative style. It supports function-style operations on streams of elements, such as map, filter and various other transformations. Streams vs Collection It is a myth that Java Stream API have replaced Collections in Java. Most of the collections are a main source for the stream to work Continue Reading
Reading Time: 5 minutes In Java, we are often tempted towards writing a code which is executed eagerly. There’s a good reason for that – eager code is easy to write and to reason about. But delaying commitments until the last responsible moment is a good agile practice. When executing the code, we can gain performance by being just a little lazy. In this blog, we will try to Continue Reading
Reading Time: < 1 minute Hi all, Knoldus has organized a 30 min session on 1st March 2019 at 3:30 PM. The topic was Alpakka – Connecting Kafka and ElasticSearch to Akka Streams. Many people have joined and enjoyed the session. I am going to share the slides here. Please let me know if you have any question related to linked slides or video. The slides of the KnolX are here: And Continue Reading
Reading Time: 3 minutes By now you must be familiar with KSQL and how to get started with it. If not, check out the Part1 KSQL: Getting started with Streaming SQL for Apache Kafka of this series. In this blog, we’ll move one step forward to get an understanding of the Dual streaming model to see what abstractions does KSQL use to process the data. All the data that we Continue Reading
Reading Time: 5 minutes As you all might have known by now that one of the hot topics for quite some time has been streaming of big data. Day after day, we see tons of streaming technologies out there competing with one another. The obvious reason for that, processing big volumes of data is not enough. We need real-time processing of data, especially when we need to handle continuously increasing Continue Reading
