smithclay Thursday, December 04, 2025Side project: exploring storing and querying OpenTelemetry data with duckdb, open table formats, and cheap object storage with some rust glue code.
Yesterday, AWS made this exact sort of data architecture lot easier with new CloudWatch features: https://aws.amazon.com/blogs/aws/amazon-cloudwatch-introduce...
Summary
This article discusses a cost-effective approach to building open-source observability pipelines using OpenTelemetry, Parquet, DuckDB, and Iceberg. It explores how these technologies can be combined to create a scalable and efficient data lake architecture for storing and analyzing observability data.
