Problem
We're a retail chain with 600 stores and a Snowflake data warehouse. Our POS terminals generate sales transactions in real time but right now they batch-upload to S3 at end of day, which means the operations team can't see intraday sales. Design a pipeline that gets POS data into Snowflake with low latency, while correctly merging with the historical data already in the warehouse.
