Hello , I wanted to check if automatic column level lineage for redshift and tableau already released ??

Hi - we don't support CLL for redshift or tableau at the moment. We have a lineage support table here - this might be helpful for you. https://datahubproject.io/docs/next/generated/lineage/lineage-feature-guide#lineage-support

Actually tableau CLL should already be supported, and automatic redshift CLL will be in the next release!
