I have been working on Scala for around 2.5 years now, but still, feel that I have yet to explore a lot in this language. There are still a lot of topics unexplored. One such topic is Monads. I have heard and read about it a lot of times but never actually got a chance to explore it. Recently I came across the term and Continue Reading
In our previous blog posts: Flinkathon: Why Flink is better for Stateful Streaming applications? Flinkathon: What makes Flink better than Kafka Streams? We saw why Apache Flink is a better choice for streaming applications. In this blog post, we will explore how easy it is to express a streaming application using Apache Flink’s DataStream API. DataStream API DataStream API is used to develop regular programs Continue Reading
This blog is for new Rustacean, who just started exploring Rust. I was exploring Rust’s Vector collection, but got confused while testing one of the Vector example of Rust Programming book. Above code won’t compile because we can’t have mutable and immutable references in the same scope. But if we write println! before pushing element into v, code will compile and execute. Here I got Continue Reading
Initially, I would like you all to focus on a few questions before comparing the frameworks:1. Is there any comparison or similarity between Flink and the Kafka?2. What could be better in Flink over the Kafka?3. Is it the problem or system requirement to use one over the other? Before talking about the Flink betterment and use cases over the Kafka, let’s first understand their Continue Reading
Knoldus has organized a session on 08th February 2019. The topic was “Understanding Spark Structured Streaming”. Many people attended and enjoyed the session. In this blog post, I am going to share the slides & video of the session. Slides: Video: If you have any query, then please feel free to comment below.
As we have already discussed in my last blog about the Type Parameterization concepts like Generics, Generic classes, and Variance. So to follow up, in this blog we’ll be discussing type bounds. Type Bounds: How can we create type parameter restrictions? To create them we make use of Scala type bounds. In Scala, Type Bounds are restrictions on Type Parameters or Type Variable. By using Type Continue Reading
Generic classes are classes which take a type as a parameter. This means, one class can be used with different types without actually writing down it multiple times. They are particularly useful for collection classes. Defining a generic class: Generic classes take a type as a parameter within square brackets [ ]. One convention is to use the letter A as type parameter identifier, though Continue Reading
In our previous post, we talked about the top IT pain points of the organizations. One of the most prominent ones is the reliance and lack of progress on innovation because of legacy systems. Legacy systems, which form the backbone of many enterprises are holding organizations back from leveraging new digital technologies and creating new experiences for their customers. Many organizations find it difficult to Continue Reading
PI (Application Programmable Interfaces) are the foundation for building your digital business, they are sets of routines, protocols, and tools for describing how software applications and components should interact with each other. They are the key driver in today’s economy for integrating with an ecosystem much larger than most companies can build on their own.
Welcome back, everyone. I have been working on Cassandra for quite some time now but never actually got to explore its working in depth. We know that its decentralized nature, as well as its ability to handle such a large volume of writes, makes it really commendable. But how does it manage to be efficient? How is it able to achieve what it is so Continue Reading
Hey folks, nowadays Big Data is the most trending topic and most of us are familiar with it as well as all the trending technologies. One of them is Druid which is a distributed, column-oriented, real-time analytical data store. A quick recap on Druid can be found on the blog posts https://blog.knoldus.com/introducing-druid-realtime-fast-data-analytics-database/. In this blog post, we will be discussing how data ingestion can be done in Continue Reading
The headline looks weird. Isn’t it. Well, there are some hidden corals in Rust sea, which you won’t find in Rust documentation. In the continuation of my exploration about Rust language, I found a useful feature unimplemented!. This feature lets you write a not-yet-implemented method, like this: The methods you define can also take input parameters and specify a return type, like this: Although your Continue Reading
