The document summarizes several data warehousing trends presented by speaker Chris Riccomini. Some of the trends discussed include: real-time data warehousing which handles hard deletes and replay from Kafka; data mesh which advocates for decentralized data ownership and treating data as a product; and headless BI which programs business metrics for use across systems rather than being confined within BI tools. The talk also covered data catalogs, reverse ETL, analytics engineering and other trends.
