Is it possible to specify the scope of Request for beans in your framework or system?

In Redis, transactions are implemented using the commands MULTI, EXEC, DISCARD, and WATCH. They allow grouping multiple commands into an atomic operation.

• MULTI starts a transaction, after which all commands are queued.
• EXEC executes all queued commands atomically.
• DISCARD cancels the transaction.
• WATCH allows monitoring keys and cancels the transaction if they change (for implementing optimistic locking).

Example in Java using Jedis:

try (Jedis jedis = new Jedis("localhost")) {
    jedis.watch("key1");
    Transaction t = jedis.multi();
    t.set("key1", "value1");
    t.incr("counter");
    List<Object> results = t.exec();
    if (results == null) {
        // transaction was canceled due to key change
    }
}

Thus, Redis transactions ensure sequential and atomic execution of a set of commands, but do not support full ACID transactions like in relational databases.
