Transactions in Redis

We’re all surrounded by transactions. Every time we buy something at a store, transfer money online, or even send a text message, we’re participating in a transaction. Transactions are an essential tool for maintaining the consistency and integrity of data in complex software systems. Without them, it would be much more difficult to ensure that data is always correct and up to date, especially in situations where multiple clients may be accessing the same data at the same time. With the increasing prevalence of distributed systems and cloud computing, transactions have become even more important. They provide a way to coordinate updates to data across multiple nodes in a system, ensuring that all nodes see a consistent view of the data at all times.
