Redis Transactions:MULTI

Redis MULTI command

Redis MULTI command is used to mark the start of a transaction block.

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

• Begin Transaction: Starts a transaction block, queuing commands for atomic execution with the EXEC command.
• Batch Command Execution: Allows multiple commands to be queued and executed as a single unit, ensuring all commands are processed together.
• Atomic Operations: Ensures that all commands within the transaction are executed atomically, or none at all if there is an error or if the transaction is aborted.
• Concurrency Control: Helps manage concurrent operations by grouping commands to avoid partial updates and ensure data consistency.
• Error Handling: Provides a way to handle errors by aborting the transaction with the DISCARD command if needed, preventing unintended changes.
