Functional Programming

Getting Started with Vault

HashiCorp Vault is a secret management tool which provides a secure and reliable way to store secrets like passwords, access token, secret API key etc.

There are applications that need to interact with third party services and for that it needs various credentials. There are scenarios in which we need different credentials to process different requests. So, where will you store them? Can you really hard-code them and publish them to your sub-versioning tool? Ofcourse not. This is not a recommendable approach.

TensorFlow with Keras part 2 using Case Study

This blog is in continuation to Part1, Tensorflow for deep learning. Make sure you go through it for a better understanding of this case study. Keras is a high-level neural networks API, written in Python and capable of running on top of Tensorflow, CNTK  or Theano. It was developed with a focus on enabling fast experimentation. In this blog, we are going to cover one Continue Reading

Big Data Evolution: Migrating on-premise database to Hadoop

We are now generating massive volumes of data at an accelerated rate. To meet business needs, address changing market dynamics as well as improve decision-making, sophisticated analysis of this data from disparate sources is required. The challenge is how to capture, store and model these massive pools of data effectively in relational databases. Big data is not a fad. We are just at the beginning Continue Reading

Scala Extractors

Scala: Extractors and Pattern Matching

An extractor in Scala is an object which has an unapply method as one of its members. Often, the extractor object also defines a method apply for building values, but this is not required. An apply method is like a constructor which takes arguments and creates an object, the unapply method takes an object and tries to give back the arguments. The unapply method reverses the construction procedure of the Continue Reading

Scala Traits – Let’s mix it up a bit

Scala has way too many unique features that have always stunned the developers worldwide. Some of its features like Lazy evaluation, case classes, etc. have totally changed the coding standards for good. In this blog today, we will be taking you on a small tour to one of these unique and mesmerizing features that Scala has in store for its users i.e Scala Trait Mixin. Continue Reading

Access multiple couchbase buckets from a Reactive Spring Boot application

A few days ago, I got a situation where I needed to access more than one couchbase bucket from a single reactive spring boot (Spring Web-flux) application. It is all about configuration. So, first of all, we will see how we can access a single couchbase bucket and then will move forward to access multiple buckets. Access Single bucket: To access a single bucket,  we Continue Reading

Using Vertica with Spark-Kafka: Write using Structured Streaming

In two previous blogs, we explored about Vertica and how it can be connected to Apache Spark. The first blog in this mini series was about reading data from Vertica using Spark and saving that data into Kafka. The next blog explained the reverse flow i.e. reading data from Kafka and writing data to Vertica but in a batch mode. i.e reading data from Kafka Continue Reading

Using Vertica with Spark-Kafka: Writing

In previous blog of this series, we took a glance over the basic definition of Spark and Vertica. We also did a code overview for reading data from Vertica using Spark as DataFrame and saving the data into Kafka. In this blog we will be doing the reverse flow i.e. working on reading the data from Kafka as a DataFrame and writing that DataFrame into Continue Reading

Using Vertica with Spark-Kafka: Reading

We live in a world of Big data where the size of data is so big even for small results. This is the result of an increase in data collection on a rapid scale in the modern world. This massiveness of data brings the requirements of such tools which can work upon such a big chunk of data. I am pretty sure that you guys Continue Reading

Scala 2.13: Has Scala done it again?
