Study Notes

Streaming and Transformation with Amazon Kinesis

Utilize Amazon Kinesis Data Firehose for real-time streaming of JSON records into destinations like Amazon S3.
Firehose automates ingestion and loading of streaming data without custom ETL processes.

Data Storage and Format

Transform JSON records into Apache Parquet format for efficient data storage.
Store transformed data in Amazon S3, utilizing the AWS Glue Data Catalog for schema definitions and metadata management.

Querying and BI Connectivity

Use Amazon Athena for executing SQL queries directly on data stored in S3, facilitating scalable analysis.
Implement the Athena JDBC connector for linking Business Intelligence (BI) tools, allowing seamless querying and data visualization.

AWS Glue Data Catalog

The AWS Glue Data Catalog serves as a centralized repository for metadata, tracking dataset definitions, physical locations, and data changes over time.

Lambda Functions and Data Transformation

An incorrect approach involves storing JSON records in S3 and triggering AWS Lambda via S3 Put events, as it does not support real-time processing and lacks a fixed buffering interval.

AWS Glue Job Notifications

S3 Event notifications can trigger AWS Lambda, Amazon SNS, or Amazon SQS but cannot directly invoke AWS Glue jobs for data processing.

Amazon Managed Streaming for Apache Kafka (MSK)

Using Amazon MSK to ingest data adds complexity with cluster management; combining with Amazon Redshift creates operational overhead, moving away from serverless architecture.

Comparison of Options

Approaches that utilize complex systems like MSK or RDS may increase operational costs and management responsibilities.
Emphasis on a serverless framework for streaming and transformation enhances cost efficiency and simplifies deployment.
