Decouple multi-source Events as a unified real-time bus with horizontal scaling (target ≤ 100 K msg/s) • Autonomous subscription and workload isolation through partitions + consumer groups • Ensure consistency and traceability with at-least-once/exactly-once semantics + replay • Incremental processing and small Batch ingestion reduce Latency to data Visualization • Avoid heavy use of Stream Load with large numbers of REST calls; use more appropriate ingestion paths • Data distribution: multiple DWH ( Redshift/ Snowflake )+ S3 Data Lake. Joins across storage systems are difficult • Athena median Latency exceeds 30 seconds • Write amplification due to redundant copies/ data consistency challenges • Unable to meet real-time requirements: Fact↔Fact Join, PK update, Point Lookup, ultra-low latency • High DWH and data transfer costs ( Redshift/ Snowflake ) • High-speed OLAP: Efficient Join, AMV ( Aggregation Materialized Views), Query Rewrite • Glue Catalog integration. Can be used standalone as an analytical engine • Operate thousands of tables/views/ AMV, PB scale Iceberg data in a single cluster • Decommissioned Druid and achieved significant savings. Reduced Snowflake usage by 95%, total cost reduced by 90% • Dashboard creation reduced from hours/days to minutes. Achieved Real-time Analytics including Point Lookup/PK updates/Fact↔Fact Join • Aligns with the vision of data exploration, silo reduction, distributed governance, and autonomous data infrastructure ≈ $ 25 B The Solution Value of Implementing StarRocks
