Vault: A secure way to keep your App’s secrets

In this blog, we will discuss the Vault. In modern scenarios, we want to secure our system as much as possible. We don’t want to store our secret keys and certificates in the system or configurations. We need a place where we can keep our secrets with more security and access them securely whenever we need them. We can use the Vault. Vault is the Continue Reading

Getting Started Dgraph: An Introduction

In our today’s blog, we will discuss the Dgraph. Dgraph is a Graph Database which gives us relief to use the traditional database. In the traditional database, we face the problem whenever we have to create them to handle the interconnected data. In our today’s scenario, there are lots of data present and those are interconnected in some way. So if we use the traditional Continue Reading

ScalaFP: Let’s discuss about Foldable

In our today’s blog, we are going to discuss a type of iterator called foldable that is used to iterate over collections. Foldable is an abstraction for the foldLeft & foldRight. We will now look in the Foldable. Foldable Foldable type class contains the foldLeft & foldRight are instances of foldable which we are used on List, Vector, and Stream. We can create generic folds with Continue Reading

ScalaFP: Let’s Start with Implicit and Scala Cats

In our last blog, we have discussed the Type Class. You can find that blog Here: Type Class. Now we will discuss the Implicit in Scala. Implicit Implicit in Scala refers to either a value that can be passed “automatically”, so to speak or a conversion from one type to another that is made automatically. So we can create the implicit method with the help of Continue Reading

ScalaFP: Let’s Start with Type Class

Before we start talking about the Functional Programming with the Scala Cats, we should refresh our memory about the Type Class and Implicit. These are the base when we start learning the Scala Cats. Let’s start the discussion with the Type Class. Type Class A type class is an interface or API that represents some functionality, which we want to implement.

IoT with the AI: Why do we need this?

Artificial Intelligence (AI) and the Internet of Things (IoT) are the next level technologies and these are getting more popular in the present time. AI makes the machine to learn from its experiences and manage with new data. AI is not a new technology but due to heavy use of big data, it is now gaining again. Similarly, IoT is the combination of more than Continue Reading

Internal working on Writing and Reading in Cassandra

Apache Cassandra is fast, distributed Database which is built for high availability and Linear Scalability with the Predictable Performance, No SPOF, Multi-DC & easy to manage. Cassandra does not follow the master-slave architecture. It uses Peer to Peer technology. Cassandra follows the features of  Availability and Partitioning from the CAP theorem. We can provide the Replication Factor for the fault tolerance and we set it Continue Reading

Store Semantic Web Triples into Cassandra

The semantic web is the next level of  Web Searching where data is more important and it should be well defined. The semantic web is needed for making the web search more intelligent and intuitive to get the user’s requirement. You all can find some interesting point on the Semantic Web here. Triples is an atomic entity in RDF. It is composed of subject-predicate-object. It Continue Reading

Welcome to the world of Riak Database !!!

Today we are going to discuss the Riak Database which is distributed NoSQL Database. In the current scenario, when there are a lot of data into the world, we can not go for the old technology for storing the data. The user wants to keep all record of their data and want to process it at lightning-fast speed, so they use Big Data technology. But Continue Reading

Getting Started Cockroach with Scala: An Introduction

Today we are going to discuss that how can we use the Scala with the Cockroach DB? As we all know that Cockroach DB is a distributed SQL database built on top of a transactional and consistent key-value store and now we are going to use it with the Scala. But before starting the journey, To those who have caught the train late,😉 this is Continue Reading
