Incremental MDE from Compose

When users create tables and views in Compose, Alation triggers a background extraction job to make the new table and view objects available in the catalog. As a result, users will see the corresponding table or view metadata in the data catalog without re-running MDE on the Settings page of the data source. When users run DDL SQL queries in Compose, incremental MDE also adds lineage information to the affected objects under the data source.
