Build an analytics pipeline that is resilient to Avro schema changes using Amazon Athena
Big Data Blog
This article provides a comprehensive guide to building an analytics pipeline that can handle Avro schema changes using Amazon Athena, AWS Glue, and Amazon S3. The solution addresses the challenges of managing evolving IoT sensor data schemas with the following key features:
- Handling frequent schema changes in IoT sensor data
- Maintaining compatibility with historical data
- Enabling querying across multiple schema versions
- Using Avro schema evolution capabilities
- Implementing partition projection for efficient data management
The solution demonstrates a step-by-step approach to: • Create an initial table in AWS Glue Data Catalog • Update the table schema as sensor capabilities evolve • Use Avro schema literals to handle schema changes • Enable partition projection for scalable querying
By combining AWS Glue, Amazon Athena, and Avro's schema evolution capabilities, organizations can build flexible and resilient analytics pipelines that adapt to changing data structures without disrupting existing analytics processes.
