Example
@info(name = 'query1')
INSERT INTO alertStream
SELECT OR(isFraud) AS isFraudTransaction
FROM cscStream WINDOW TUMBLING_LENGTH(10);
This query, named 'query1', processes records from the cscStream in tumbling windows of length 10. It calculates the logical OR of the isFraud field using the OR(isFraud) function. If at least one record in the window has isFraud set to true, then the resulting isFraudTransaction will be true. The calculated isFraudTransaction value is then inserted into the alertStream.
Essentially, this query identifies if there's any fraudulent transaction within a window of 10 records in the cscStream, and then creates new records in the alertStream with the isFraudTransaction field.
