Apache Cassandra is a highly scalable, distributed, and fault-tolerant NoSQL database that is widely used for managing large amounts of structured data across multiple commodity servers. One of the key features of Cassandra is its ability to replicate data across multiple nodes in a cluster, providing fault tolerance and high availability. In this article, we will discuss how to change the replication factor of a Cassandra cluster, and the considerations to keep in mind when doing so. Introduction to Replication Factor The replication factor in Cassandra refers to the number of copies of each piece of data that are stored ... Read More

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

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

Blob conversion function in Cassandra

Raunak Jain
Updated on 10-Jan-2023 18:22:08
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
