Common connectors (JDBC, S3, Elasticsearch) in Kafka - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the JDBC connector in Kafka?

The JDBC connector allows Kafka to connect to relational databases. It can read data from databases into Kafka topics or write data from Kafka topics back into databases.

beginner

How does the Kafka S3 connector help in data handling?

The Kafka S3 connector moves data between Kafka topics and Amazon S3 storage. It can save Kafka data as files in S3 or read files from S3 into Kafka.

beginner

What role does the Elasticsearch connector play in Kafka?

The Elasticsearch connector sends data from Kafka topics to an Elasticsearch cluster. This helps in searching and analyzing data quickly.

beginner

Which Kafka connector type is used to import data into Kafka topics?

Source connectors are used to import data into Kafka topics from external systems like databases or storage services.

beginner

What is a sink connector in Kafka?

A sink connector takes data from Kafka topics and sends it to external systems like databases, S3, or Elasticsearch for storage or processing.

Which Kafka connector would you use to export data from Kafka to a relational database?

A S3 source connector

B JDBC sink connector

C Elasticsearch source connector

D Kafka Streams

The JDBC sink connector writes data from Kafka topics into relational databases.

What does the Kafka S3 connector primarily do?

A Transfers data between Kafka and Amazon S3

B Indexes data in Elasticsearch

C Connects Kafka to relational databases

D Processes streams inside Kafka

The S3 connector moves data between Kafka topics and Amazon S3 storage.

Which connector type reads data from external systems into Kafka?

A Sink connector

B Stream connector

C Processor connector

D Source connector

Source connectors import data into Kafka topics from outside systems.

What is the main use of the Elasticsearch sink connector in Kafka?

A To send Kafka data to Elasticsearch for search and analysis

B To read data from Elasticsearch into Kafka

C To store Kafka data in Amazon S3

D To connect Kafka to relational databases

The Elasticsearch sink connector sends Kafka topic data to Elasticsearch clusters.

Which of the following is NOT a typical Kafka connector?

A Elasticsearch connector

B S3 connector

C FTP connector

D JDBC connector

FTP connector is not a common Kafka connector; JDBC, S3, and Elasticsearch connectors are standard.

Explain how Kafka connectors help integrate Kafka with databases, cloud storage, and search engines.

Think about how data moves between Kafka and other systems.

Describe the difference between source and sink connectors in Kafka with examples.

Focus on the direction of data flow.
