MirrorMaker 2 concept in Kafka - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is MirrorMaker 2 in Kafka?

MirrorMaker 2 is a tool in Kafka used to replicate data between Kafka clusters. It helps keep data synchronized across different environments or data centers.

How does MirrorMaker 2 differ from MirrorMaker 1?

MirrorMaker 2 is built on the Kafka Connect framework, offering better scalability, fault tolerance, and easier configuration compared to MirrorMaker 1, which was a simpler, standalone tool.

What are the main components of MirrorMaker 2?

MirrorMaker 2 uses Kafka Connect source and sink connectors to read from the source cluster and write to the target cluster. It also manages offsets and consumer groups to ensure reliable replication.

Why is offset translation important in MirrorMaker 2?

Offset translation allows MirrorMaker 2 to map consumer offsets from the source cluster to the target cluster, so consumers can continue reading messages seamlessly after failover or migration.

advanced

Can MirrorMaker 2 handle bi-directional replication?

Yes, MirrorMaker 2 supports active-active setups where data is replicated in both directions between clusters, helping with high availability and disaster recovery.

What framework is MirrorMaker 2 built on?

A Kafka Connect

B Zookeeper

C Kafka Streams

D Apache Flink

MirrorMaker 2 uses Kafka Connect framework to manage connectors for replication.

What is the main purpose of MirrorMaker 2?

A To monitor Kafka brokers

B To process streaming data

C To replicate data between Kafka clusters

D To store data permanently

MirrorMaker 2 replicates data between Kafka clusters to keep them synchronized.

Which feature helps MirrorMaker 2 maintain consumer position after failover?

A Offset translation

B Topic compaction

C Partition reassignment

D Consumer lag monitoring

Offset translation maps consumer offsets from source to target cluster.

MirrorMaker 2 supports which type of replication?

A Uni-directional only

B Bi-directional

C File-based

D Database replication

MirrorMaker 2 supports bi-directional replication for active-active cluster setups.

Which of these is NOT a component of MirrorMaker 2?

A Source connector

B Sink connector

C Offset translator

D Kafka Streams processor

MirrorMaker 2 does not use Kafka Streams processors; it uses Kafka Connect connectors.

Explain how MirrorMaker 2 replicates data between Kafka clusters.

Think about how data moves from one cluster to another and how consumer positions are kept.

Describe the benefits of using MirrorMaker 2 over MirrorMaker 1.

Consider improvements in architecture and reliability.
