What could be the reason for the warning in the logs regarding missing field in a materialized view based on a Kafka topic with JSON data?
Igor Artamonov is experiencing a warning in the logs related to missing fields in a materialized view based on a Kafka topic with JSON data. The warning indicates that some messages do not contain a specific field (childid) and are being padded with NULL. Igor is concerned about the warning spamming the log output and potentially missing important information. tianshuo shi explains that the warning is intentional and suggests ignoring it. Additionally, tianshuo shi mentions that only 1 log per second is allowed and suppressed logs are counted in suppressed_count in the warning message. Igor is reassured that the warning is normal and not impacting performance.

- The warning in the logs is generated because some messages in the Kafka topic do not contain the
childidfield. - The system is padding these messages with NULL values to handle the missing field.
- The warning is intentional to alert users about this situation.
- Suppressed logs are counted in
suppressed_countin the warning message. - The system limits log output to 1 log per second to prevent performance issues.
- Igor can ignore the warning as it is a normal situation and does not impact the system's functionality.
