Append Timestamp column to exported Kafka messages
I successfully configured data export from Kafka and see messages in Vertica table public.kafka_tgt
It consists __identity__ and __raw__ columns.
Basically I want to create aggregations for every second of data (e.g. number of specific event per second, or per hour, or per year and so on).
Is it possible to add column with timestamp to exported Kafka data? Or is it possible to get aggreagates in some other way?
