Amazon-DEA-C01 Exam - Topic 4 Question 15 Discussion

Actual exam question for Amazon's Amazon-DEA-C01 exam

Question #: 15
Topic #: 4

A company has a gaming application that stores data in Amazon DynamoDB tables. A data engineer needs to ingest the game data into an Amazon OpenSearch Service cluster. Data updates must occur in near real time.

Which solution will meet these requirements?

AUse AWS Step Functions to periodically export data from the Amazon DynamoDB tables to an Amazon S3 bucket. Use an AWS Lambda function to load the data into Amazon OpenSearch Service.

BConfigure an AW5 Glue job to have a source of Amazon DynamoDB and a destination of Amazon OpenSearch Service to transfer data in near real time.

CUse Amazon DynamoDB Streams to capture table changes. Use an AWS Lambda function to process and update the data in Amazon OpenSearch Service.

DUse a custom OpenSearch plugin to sync data from the Amazon DynamoDB tables.

Show Suggested Answer

Suggested Answer: C

Problem Analysis:

The company uses DynamoDB for gaming data storage and needs to ingest data into Amazon OpenSearch Service in near real time.

Data updates must propagate quickly to OpenSearch for analytics or search purposes.

Key Considerations:

DynamoDB Streams provide near-real-time capture of table changes (inserts, updates, and deletes).

Integration with AWS Lambda allows seamless processing of these changes.

OpenSearch offers APIs for indexing and updating documents, which Lambda can invoke.

Solution Analysis:

Option A: Step Functions with Periodic Export

Not suitable for near-real-time updates; introduces significant latency.

Operationally complex to manage periodic exports and S3 data ingestion.

Option B: AWS Glue Job

AWS Glue is designed for ETL workloads but lacks real-time processing capabilities.

Option C: DynamoDB Streams + Lambda

DynamoDB Streams capture changes in near real time.

Lambda can process these streams and use the OpenSearch API to update the index.

This approach provides low latency and seamless integration with minimal operational overhead.

Option D: Custom OpenSearch Plugin

Writing a custom plugin adds complexity and is unnecessary with existing AWS integrations.

Implementation Steps:

Enable DynamoDB Streams for the relevant DynamoDB tables.

Create a Lambda function to process stream records:

Parse insert, update, and delete events.

Use OpenSearch APIs to index or update documents based on the event type.

Set up a trigger to invoke the Lambda function whenever there are changes in the DynamoDB Stream.

Monitor and log errors for debugging and operational health.

I think I saw a practice question similar to this, and it emphasized using Lambda with DynamoDB Streams. That makes me lean towards option C as well.

I'm not entirely sure, but I feel like AWS Glue jobs are more for batch processing. Option B might not meet the near real-time requirement.

Option C seems like the best fit for this scenario. The combination of DynamoDB Streams and a Lambda function is a well-established pattern for real-time data integration. It should be relatively easy to implement and maintain, and it should meet the near real-time requirement.

This is a tricky one. I'm leaning towards option D, using a custom OpenSearch plugin to sync the data directly. That might be the most efficient approach, but it could also be more complex to set up and maintain. I'd need to weigh the pros and cons carefully.

I think option C is the way to go here. Using DynamoDB Streams and a Lambda function is a common pattern for keeping data in sync between different systems. It should give you the near real-time updates you need, and it's a relatively straightforward implementation.

Hmm, I'm a bit unsure about this one. I'm not super familiar with DynamoDB Streams, so I'm not sure if that's the best approach. Option B with AWS Glue might be a simpler solution, but I'd need to look into the capabilities of Glue to make sure it can handle the near real-time requirement.

This looks like a pretty straightforward data ingestion problem. I think I'd go with option C - using DynamoDB Streams and a Lambda function to update the OpenSearch cluster. That seems like the most direct way to get the data into OpenSearch in near real-time.
