Let’s consider a task: developing a good morning greeting system that supports both English and Hebrew languages. The system should greet us in each of these languages.
We’ll begin with the native implementation by introducing our greeters:
Around a year ago, my team and I were tasked with building a high-performance system capable of handling a large volume of requests. After careful consideration, we chose Cassandra as our database.
