Hello I have a question, when running ingestion on a schedule, does datahub read the entire source or does it only look at the changes that have been made to the source since the last ingestion run? e.g. if I connect to snowflake, and there are three tables A, B, C the first time ingestion is run, and after the first ingestion run if only C has changes, will datahub re-read A, B, and C or will it only look at C? Thanks!
Hey there! 
Make sure your message includes the following information if relevant, so we can help more effectively!
- Are you using UI or CLI for ingestion?
- Which DataHub version are you using? (e.g. 0.12.0)
- What data source(s) are you integrating with DataHub? (e.g. BigQuery)
I am using the UI for ingestion, v0.12.1, and we’re integrating snowflake, vertica, postgres, tableau, s3, airflow
