Redis QuickStart-Redis transactions (13)

Redis transactions let a set of commands execute in a single step. There are two properties in the transaction, which are described below:

• All commands in a transaction are executed sequentially as a single, independent operation. This is not possible, and requests made to another client are held during the execution of the Redis transaction.
• Redis transactions are also atomic. An atom means that either all commands are executed, or none are processed.

Example

The Redis transaction is started by the instruction MULTI, and then the transaction is passed, and the entire transaction executes after executing the command, executing a list of commands.

Redis 127.0.0.1:6379> MULTI

Ok

List of commands here

Redis 127.0.0.1:6379> EXEC

Example

Here's an example of how Redis's bookstore is started and executed.

Redis 127.0.0.1:6379> MULTI

Ok
Redis 127.0.0.1:6379> Set Tutorial Redis

QUEUED

Redis 127.0.0.1:6379> GET Tutorial

QUEUED

Redis 127.0.0.1:6379> INCR Visitors

QUEUED

Redis 127.0.0.1:6379> EXEC

1) OK

2) "Redis"

3) (integer) 1
