5 Reasons to Use Cassandra For Building Your Newsfeed
Blog post from Stream
When deciding whether to use Redis or Cassandra for powering newsfeeds with the open-source Stream-Framework, Cassandra is recommended in certain scenarios due to its cost-effectiveness, scalability, and data management features. Cassandra stores data on disk, providing a cost advantage over Redis, which stores data in memory and can become expensive, especially in cloud hosting environments. It also offers automatic data sharding and replication across nodes, ensuring high availability and facilitating easy capacity expansion as user bases grow. Cassandra's powerful opscenter monitoring tool provides valuable insights into cluster health and usage. It is particularly suitable for handling rapid growth, supporting aggregated feeds, and managing large user bases more affordably than Redis. Although Cassandra requires time to learn and maintain, it avoids the need for complex Redis resharding mechanisms and can offer significant cost savings when infrastructure bills for Redis exceed a certain threshold. The Stream-Framework supports both Redis and Cassandra, and for a more comprehensive solution, getstream.io offers a REST API based on an optimized Cassandra cluster.
