Using Kafka Headers as Columns in ClickHouse Table Engine

[Sateesh Kommineni]

Hi,

  I am in the process of creating ClickHouse Tables using KafkaTable Engine and wondering how i can get the Kafka Headers as Table Colums. Is this supported ? i haven't found a any info related to this in the Documentation.

  And also the Kafka Topic i am going to use as Source has the data in XML. Since XML as input is not supported how does it appear in the created table ?

Thanks

Kafka headers should be accessible as virtual columns along with other
virtual columns.

SELECT
_topic,
_key,
_offset,
_partition,
_timestamp,
_timestamp_ms,
_headers.name,
_headers.value
FROM queue
LIMIT 10
