Cross-datacenter replication in Kafka - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the source Kafka cluster for replication.

Kafka

replication.source.cluster = "[1]"

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

💡 Hint

Common Mistakes

Confusing source and destination cluster names.

Using region names instead of cluster identifiers.

The source cluster is the Kafka cluster where data originates. Here, it is named "source-cluster".

medium

Complete the code to specify the destination Kafka cluster for replication.

Kafka

replication.destination.cluster = "[1]"

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

💡 Hint

Common Mistakes

Mixing up source and destination cluster names.

Using unrelated cluster names.

The destination cluster is where the data is replicated to. It is named "destination-cluster" here.

hard

Fix the error in the replication topic configuration to enable replication.

Kafka

replication.topic = "[1]"

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

💡 Hint

Common Mistakes

Using generic or incorrect topic names.

Confusing topic names with cluster names.

The replication topic must be correctly named to match the source topic being replicated. "replicated-topic" is the correct name here.

4fill in blank

hard

Fill both blanks to configure the replication factor and the number of partitions for the replicated topic.

Kafka

replication.topic.config = {"replication.factor": [1], "partitions": [2]

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

💡 Hint

Common Mistakes

Setting replication factor too low or too high.

Choosing too few partitions for workload.

The replication factor is set to 3 to ensure fault tolerance, and the number of partitions is set to 10 for parallelism.

5fill in blank

hard

Fill all three blanks to complete the replication configuration with topic name, replication factor, and partitions.

Kafka

replication.config = {"topic": "[1]", "replication.factor": [2], "partitions": [3]

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

💡 Hint

Common Mistakes

Using source topic name instead of replicated topic.

Incorrect replication factor or partition count.

The topic to replicate is "replicated-topic" with a replication factor of 3 and 10 partitions for performance and reliability.
