1. Use the TUMBLE function to create fixed-size windows based on the timestamp column.
2. Filter for 'Failure' events in the auth column.
3. Group the results by user_id or source_ip using the GROUP BY clause.
4. Count the number of failure attempts within each window and group.
5. Adjust the queries based on your specific requirements and schema details.
6. Ensure that the function names are correctly implemented and supported in RisingWave.

Example queries:

Grouped by user_id

SELECT
  TUMBLE_START("timestamp", INTERVAL '10' MINUTE) AS window_start,
  user_id,
  COUNT(*) AS failure_attempts
FROM
  auth_logs
WHERE
  "timestamp" >= NOW() - INTERVAL '10' MINUTE
  AND auth = 'Failure'
GROUP BY
  TUMBLE("timestamp", INTERVAL '10' MINUTE),
  user_id
HAVING
  COUNT(*) > 1;

Grouped by source_ip

SELECT
  TUMBLE_START("timestamp", INTERVAL '10' MINUTE) AS window_start,
  source_ip,
  COUNT(*) AS failure_attempts
FROM
  auth_logs
WHERE
  "timestamp" >= NOW() - INTERVAL '10' MINUTE
  AND auth = 'Failure'
GROUP BY
  TUMBLE("timestamp", INTERVAL '10' MINUTE),
  source_ip
HAVING
  COUNT(*) > 1;
