Data ingestion refers to the process of obtaining, importing, and processing data for immediate use or storage in the database. In the context of the AWS Certified Solutions Architect – Associate (SAA-C03) exam, understanding varying data ingestion patterns, including frequency, becomes significantly important.
The frequency of data ingestion can vary according to the requirements of specific use cases. Some applications may require real-time ingestion, while some would only need periodic or batch-based data ingestion. Using AWS, we can efficiently implement different data ingestion patterns, enabling architectures that suit best for the operational needs.
Data ingestion patterns
Here, we will discuss different data ingestion patterns that are important in relation to the AWS Certified Solutions Architect – Associate exam.
1. Real-Time Data Ingestion: Kinesis and Lambda
Real-time data ingestion involves constant integration and immediate processing of the data. In AWS, we can use the likes of Kinesis Data Streams with AWS Lambda to fulfill this requirement. An example can be a social media app streaming real-time user activities or a connected IoT device sending live sensor data. Kinesis Data Stream will ingest data real time and triggers AWS Lambda to process data in near real-time.
2. Batch-Based Data Ingestion: S3 and Glue
Batch-based data ingestion is scheduled at specific intervals rather than real-time. It is typically executed at a slower frequency compared to real-time ingestion patterns. AWS Glue and S3 can be used to implement batch-based ingestion. For instance, consider the use case of loading the end-of-day sales data from various stores into an S3 bucket. AWS Glue can be used to run ETL jobs that process and load data into an AWS-based analytics platform.
3. Stream-Batch Hybrid Ingestion: Kinesis Data Firehose
Some scenarios may require a hybrid between the stream & batch ingestion patterns like Kinesis Data Firehose which can cater to both real-time and batch-based data processing requirements. For instance, real-time analytical processing and the same data can also be batch-processed for extensive data analytics.
A comparative look
Let’s have a comparative look at the mentioned data ingestion patterns.
| Data Ingestion Pattern | AWS Services | Use Case |
|---|---|---|
| Real-Time Ingestion | Kinesis Data Streams & Lambda | Streaming live user activities |
| Batch-Based Ingestion | S3 & Glue | Loading end-of-day sales data |
| Stream-Batch Hybrid | Kinesis Data Firehose | Real-time analytics and extensive batch data analysis |
Conclusion
Finally, it’s imperative to point out that these patterns are not exclusive, rather, they can be combined as per the unique requirements of your application. Understanding these patterns is an important aspect for the AWS Certified Solutions Architect – Associate exam, because they offer an efficient way to process, store, analyze, and retrieve data, which is a critical part of architecting on AWS.
