5. Perform Data Modeling Through Cassandra
This is one of the interesting data engineering projects to create. Apache Cassandra is an open-source NoSQL database management system that enables users to use vast quantities of data. Its main benefit is it allows you to use the data spread across multiple commodity servers, which mitigates the risk of failure. Because your data is spread across various servers, one server’s failure wouldn’t cause your entire operation to shut down. This is just one of the many reasons why Cassandra is a popular tool among prominent data professionals. It also offers high scalability and performance.
In this project, you’d have to perform data modelling by using Cassandra. However, when modelling data through Cassandra, you should keep a few points in mind. First, make sure that your data is spread evenly. It is one of the trending data engineering projects. While Cassandra helps in ensuring an even spread of your data, you’d have to double-check this for surety.
Secondly, use the smallest amount of partitions the software reads while modelling. That’s because a high number of reading partitions would put an added load on your system and hamper overall performance. After finishing this project, you’d be familiar with multiple features and applications of Apache Cassandra.
Apart from the ones mentioned here, you can also choose to take up projects about data engineering examples used in the real world. Here’s a list of some other projects on data engineering examples:
