How Seltz cut data costs 40% with Amazon S3 Tables
Seltz operates a web search engine for artificial intelligence (AI) agents where information freshness is critical. Its Knowledge Pipeline processes billions of documents through a sequence of enrichment steps (text extraction, quality scoring, deduplication, vectorization) to produce structured knowledge that AI agents can reason over. Building and operating a pipeline at this scale demanded significant engineering time and cost, so Seltz turned to Amazon S3 Tables.

Build Slowly Changing Dimensions Type 2 (SCD2) with Apache Spark and Apache Hudi on Amazon EMR
Organizations across the globe are striving to improve the scalability and cost efficiency of the data warehouse. Offloading data and data processing from a data warehouse to a data lake empowers companies to introduce new use cases like ad hoc data analysis and AI and machine learning (ML), reusing the same data stored on Amazon Simple Storage Service (Amazon S3). This approach avoids data silos and allows you to process the data at very large scale while keeping the data access cost-effective.
