Real-time update of entity details

Atlas cannot update row numbers for entities unless a Data Definition Language operation is made on the entity.

Atlas can only monitor events caused by the DDL commands. This means that Atlas is not updated when Data Manipulation Language (DML) operations (SELECT/INSERT/UPDATE/DELETE) cause changes in Hive. Details not updated include also the operational properties, for example, lastAccessTime, last_modified_by, last_modified_time. The displayed details in Atlas (for example, number of rows) can be triggered by Data Definition Language (DDL) operations (CREATE/ALTER/DROP).

You can check the number of rows in Hue with the Table Browser.

You can also check the number of rows by using the COUNT query.
