'Clickhouse Kafka engine virtual column _timestamp meaning
In the Clickhouse Kafka engine, there are some virtual columns containing the _timestamp or _timestamp_ms fields.
Any idea what do these fields exactly mean? When the message
- was sent to Kafka
- was consumed by Clickhouse
- was stored to Clickhouse
Or something different?

it is the timestamp from the kafka message. https://kafka.apache.org/20/javadoc/org/apache/kafka/clients/producer/ProducerRecord.html

It is set by your producer or your broker
