For example, this is the schema of the ecommerce orders table: When we look at a table schema, it is quite similar to the table definition of relational database. That also means that scaling up can simply be done by adding nodes to the cluster. While traditional databases mainly rely on a master node for the processing of queries, the design of Cassandra is masterless which allows multiple nodes to handle massive volumes of queries in parallel. The fundamental design of Cassandra is a distributed database, it splits data tables into partitions and spreads across multiple nodes. You will get to know the concepts of data partitioning and table design of Cassandra database.Ĭassandra was first built at Facebook for its inbox search feature over a decade ago. If you are new to Cassandra and would like to have a quick introduction, you will find this article useful as it provides you a step-by-step hands-on practice on Cassandra from table creation to data query. Similarly, your system won’t speed up but only suffer from the drawbacks if you use Cassandra as if it were a relational database. Unfortunately, a powerful tool is completely useless if you do not fully understand its usage. Hence, many tech companies adopted Cassandra for the implementation of their high performance systems. While conventional databases respond to data queries within milliseconds, Cassandra database could achieve the performance of microseconds, it is around 10x or even 100x times faster. Therefore, you better consider alternative options such as the type of NoSQL database which is built for high performance.Ĭassandra database is renowned for its excellent performance. If performance of your database still bothers you and does not fulfill the demand after fine-tuning, then your relational database has probably reached the limit. However, system I/O is unavoidable as most business functions involve data retrieval and update.Īlthough most modern relational databases are optimized for performance, it is challenging to meet the ever growing demand on performance. In spite of fast CPU and powerful infrastructure, system I/O such as database access remains a bottleneck of most system processes. If your website takes over 1 second to provide a response, your online business would probably suffer because most potential customers do not have the patience and simply switch to other websites. Fast response is crucial to successful online businesses.
