Consumer Offset Commit Strategies

The video tutorial discusses two common strategies for committing offsets in a consumer application: enabling autocommit and manually committing offsets. The first strategy, autocommit equals true, is the default and involves synchronous processing of batches. However, it can be risky if asynchronous processing is used, as offsets may be committed before data is processed. The second strategy, autocommit equals false, allows for manual control over when offsets are committed, providing more control and reducing risk. The tutorial provides examples and pseudocode to illustrate these strategies.

What are the two most common strategies for committing offsets in a consumer application?

• Synchronous and asynchronous processing

• Batch processing and real-time processing

• Enabling autocommit and manual commit

• Offset tracking and data buffering

What is the default behavior of enabling autocommit in consumer applications?

• Offsets are committed manually by the user

• Offsets are committed automatically at regular intervals

• Offsets are committed only after data processing

• Offsets are never committed

Why is enabling autocommit considered risky, especially for beginners?

• It requires complex configuration

• It is not compatible with Elasticsearch

• Offsets may be committed before data is processed

• It does not support batch processing

What is a key advantage of using manual commit for offsets?

• Offsets are committed without user intervention

• Users have control over when offsets are committed

• Offsets are committed based on a fixed schedule

• Offsets are committed automatically

In the manual commit strategy, when are offsets typically committed?

• After a batch of records is processed and flushed to a database

• At the start of data processing

• Offsets are never committed

• After every message is processed
