About Column level lineage
K has the ability to processes queries its captures to provide column level lineage.
This process is currently a BETA feature and is run manually. The initial run will process all queries that are currently used in lineage and may take some time to complete (~50K queries per hour). Subsequent runs will be significantly shorter as only new queries are processed. Whilst this feature is in BETA we recommend running the initial run out of business hours.
