      kafka_topic_name as topic_name,
      kafka_partition as partition_id,
      kafka_offset as offset,
      kafka_timestamp as timestamp,
      kafka_key as key,
      kafka_value as value
      FROM
      kafka_consumer_table
      WHERE
      kafka_timestamp > (CURRENT_TIMESTAMP – INTERVAL ‘1 hour’)
      REFRESH MATERIALIZED VIEW mv_kafka_to_redshift WITH GRANT SELECT ON TABLE mv_kafka_to_redshift TO redshift_user;
    2. Stream the casting process for the message payload knowledge sort to Amazon Redshift’s super sort.
    3. Automatically refresh the materialized view.
CREATE MATERIALIZED VIEW iot_telemetry_view  REFRESH FAST ON COMMIT AS  SELECT      kafka_partition,      kafka_offset,      kafka_timestamp_type,      kafka_timestamp,      SUPER(CAST(kafka_value AS SUPER)) AS payload FROM kafka_schema.iot_telemetry_topic;
  1. Question the iot_telemetry_view Materialized view enables real-time ingestion of IoT telemetry data from Kafka streams. The materialized view will automatically refresh whenever new data becomes available in the Kafka topic.
SELECT    kafka_timestamp AS Timestamp,    device_id AS Device_ID,    temperature AS Temperature,    stress AS Stress  FROM iot_telemetry_view;

By leveraging this implementation, you’ll gain near-instant insights into IoT system performance metrics through seamless integration with Amazon Redshift’s real-time data ingestion capabilities. As telemetry data is gathered by the MSK matter, Amazon Redshift seamlessly ingests and presents the information within a materialized view, enabling prompt analysis and inquiry into the data in near real-time fashion.
