Hi How does datahub decide whether a column is nullable or not. We have various tables whose create table does not include nullable true but still datahub renders the columns as nullable PFB screenshot. datahub version: v0.8.45

In which source did you see this? This depends on the source.

oracle

we use Sqlalchemy under the hood in this case and the driver gives us back if it is nullable or not -> https://docs.sqlalchemy.org/en/14/dialects/oracle.html

how does the driver detect it ?
