Consumer Part 2 - Write the Consumer and Send to Elasticsearch

The video tutorial explains how to transfer data from a Kafka topic to Elasticsearch using a custom consumer. It covers setting up the consumer, configuring it, polling data, processing records, and inserting them into Elasticsearch. The tutorial demonstrates running the code and verifying the data insertion, highlighting the importance of proper configuration and testing.

What is the primary goal of the task described in the first section?

• To update the Kafka producer

• To transfer data from Kafka to Elasticsearch

• To create a new Kafka topic

• To delete data from Elasticsearch

Which configuration is crucial for ensuring the consumer reads from the beginning of the Kafka topic?

• Group ID

• Auto offset reset

• Key deserializer

• Bootstrap server

What is the purpose of the 'while true' loop in the consumer code?

• To reset the consumer offset

• To initialize the consumer

• To continuously poll for new data

• To stop the consumer after a fixed time

What is the role of the 'index request' in the process?

• To insert data into Elasticsearch

• To update the Kafka topic

• To delete data from Elasticsearch

• To create a new Kafka consumer

How is the data formatted when inserted into Elasticsearch?

• As plain text

• As XML

• As a JSON document

• As a CSV file

What is the effect of introducing a delay in the data insertion process?

• It slows down the data insertion

• It speeds up the data insertion

• It duplicates the data in Elasticsearch

• It deletes the data after insertion

What future improvements are suggested for the code?

• Changing the data format to XML

• Removing the consumer entirely

• Optimizing the code for speed

• Adding more Kafka topics
