💡 Hint

Common Mistakes

Using 'transaction' instead of 'pipeline'.

Trying to use 'multi' which is a Redis command but not the client method.

To start a Redis pipeline, you call the pipeline() method on the client.

2fill in blank

medium

Complete the code to add a command to the pipeline.

Redis

pipe.[1]('set', 'key', 'value')

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'execute' which runs the pipeline immediately.

Using 'send_command' which is not a standard pipeline method.

The method execute_command adds a command to the pipeline queue.

3fill in blank

hard

Fix the error in the code to run the pipeline and get results.

Redis

results = pipe.[1]()

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'run' which is not a Redis pipeline method.

Using 'commit' which is a database term but not for Redis pipelines.

The correct method to run all queued commands in a Redis pipeline is execute().

4fill in blank

hard

Fill both blanks to create a pipeline, add a command, and execute it.

Redis

pipe = client.[1]()
pipe.[2]('get', 'key')
results = pipe.execute()

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'transaction' instead of 'pipeline' to start.

Using 'send_command' instead of 'execute_command' to add commands.

First, create the pipeline with pipeline(), then add commands with execute_command().

5fill in blank

hard

Fill all three blanks to create a pipeline, add two commands, and execute them.

Redis

pipe = client.[1]()
pipe.[2]('set', 'a', '1')
pipe.[3]('get', 'a')
results = pipe.execute()

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'transaction' instead of 'pipeline' to start.

Using 'send_command' which is not the standard method to add commands.

Start the pipeline with pipeline(), then add commands with execute_command() twice before executing.
