Description: An isolated transaction in Redis refers to a set of operations that are executed independently of other transactions. This means that during the execution of an isolated transaction, the changes made are not visible to other transactions until the transaction is complete. This approach ensures that operations are atomic, meaning they either fully execute or do not execute at all, which helps maintain data integrity. In general, transactions in databases are implemented using commands that allow for grouping operations and ensuring they are executed in a defined order. By grouping commands into a transaction, a set of operations can be performed together, and upon authorization, all commands are executed in the order they were added. If the transaction needs to be aborted, commands can be issued to discard the changes. The isolation feature is crucial in environments where multiple clients may be accessing and modifying the same data simultaneously, as it prevents race conditions and ensures that data remains consistent.
