Redis

pipe = client.[1]()

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

💡 Hint

Common Mistakes

Using 'connect' instead of 'pipeline' to start a pipeline.

Trying to execute commands without starting a pipeline.

To start a pipeline in Redis client libraries, you call pipeline() on the client object.

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

Calling 'set' directly on the pipeline object instead of 'send_command'.

Using 'execute' before adding commands.

To add a command to the pipeline, use send_command with the command name and arguments.

3fill in blank

hard

Fix the error in the code to execute the pipeline.

Redis

💡 Hint

Common Mistakes

Calling 'send_command' instead of 'execute' to run the pipeline.

Trying to call 'pipeline' again instead of executing.

To run all commands in the pipeline and get results, call execute().

4fill in blank

hard

Fill both blanks to create a pipeline and add a GET command.

Redis

pipe = client.[1]()
pipe.[2]('get', 'mykey')

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

💡 Hint

Common Mistakes

Using 'execute' to add commands instead of to run them.

Trying to connect instead of creating a pipeline.

First, create a pipeline with pipeline(), then add commands with send_command().

5fill in blank

hard

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

Redis

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

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

Apipeline

Bsend_command

Cexecute

Dflush

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'flush' instead of 'execute' to run the pipeline.

Adding commands with 'execute' instead of 'send_command'.

Start the pipeline with pipeline(), add commands with send_command(), and run all commands with execute().
