Redis Transactions: EXEC

Redis EXEC Command

Redis EXEC command is used to execute all previously queued commands in a transaction and restores the connection state to normal.

Here are some common uses and scenarios for the "EXEC" command:

• Commit Transaction: Executes all commands queued in a transaction started with the MULTI command, applying changes atomically.
• Atomic Operations: Ensures that a series of commands are executed as a single, atomic operation, either all succeeding or all failing.
• Batch Processing: Facilitates batch processing by allowing multiple commands to be processed together, reducing round-trip time.
• Consistency: Maintains data consistency by applying all commands in the transaction as a unit, ensuring no partial updates.
