NoSQL databases, which stand for "not only SQL, " are a popular alternative to traditional relational databases. They are designed to handle large amounts of unstructured or semi-structured data, and are often used for big data and real-time web applications. However, like any technology, NoSQL databases come with their own set of challenges. Challenges of NoSQL Data modeling and schema design One of the biggest challenges with NoSQL databases is data modeling and schema design. Unlike relational databases, which have a well-defined schema and a fixed set of tables, NoSQL databases often do not have a fixed schema. This can ... Read More

Cassandra: An Introduction to the Distributed NoSQL Database In today's fast-paced digital world, the volume and velocity of data generated is increasing at an unprecedented rate. To handle this big data, traditional relational databases such as MySQL and PostgreSQL are no longer sufficient. This is where NoSQL databases come into the picture, and one of the most popular NoSQL databases is Apache Cassandra. In this article, we will introduce you to the basics of Cassandra, a highly-scalable, distributed NoSQL database that is known for its ability to handle large amounts of data across multiple commodity servers. We will cover the ... Read More

Introduction Bulk reading is a common operation when working with Cassandra, a popular NoSQL database known for its scalability and high performance. It allows you to efficiently retrieve large amounts of data from a Cassandra cluster by making use of the database's distributed architecture. In this article, we'll explore the various ways you can perform bulk reading in Cassandra and the considerations you should keep in mind when doing so. What is Cassandra? Before diving into the specifics of bulk reading, let's first take a step back and talk about Cassandra itself. Cassandra is a distributed database management system designed ... Read More

Introduction If you are working with Cassandra, you may have come across the need to convert blobs to other data types or vice versa. Cassandra, being a distributed NoSQL database, stores data in the form of blobs (binary large objects) to increase flexibility and scalability. However, this can cause issues when you need to query or manipulate the data stored as blobs. That's where the blob conversion function comes in handy. In Cassandra, you can use the "blobAs*" function to convert blobs to various data types, such as integers, floats, timestamps, and more. This function allows you to easily access ... Read More
