While this +architecture appears to be well-suited for T+1 scenarios, as more attention is paid to applying Lakehouse to streaming data warehouses and real-time +analysis scenarios, challenges arise. For example: + +- Streaming writes bring a massive amount of fragment files +- CDC ingestion and streaming updates generate excessive redundant data +- Using the new data lake format leads to orphan files and expired snapshots. + +These issues can significantly affect the performance and cost of data analysis. Therefore, Amoro has introduced a Self-optimizing mechanism to +create an out-of-the-box Streaming Lakehouse management service that is as user-friendly as a traditional database or data warehouse. The new table +format is used for this purpose. Self-optimizing involves various procedures such as file compaction, deduplication, and sorting. Review Comment: I believe it is a streaming-enhanced table format based on Iceberg. The table format essentially extends Iceberg by combining two Iceberg tables. We can remove this statement as it lacks clarity in the current context. -- This is an automated message from the Apache Git Service.
