Select the checkboxes for all the tables that need to be validated.
Click on Add Selected at the bottom.
Advanced Options
For large tables, it is recommended to provide a partition column so Vexdata can pull the data in parallel. Vexdata can autodetect the partition column; however, it is recommended that users provide this partition.
Rules for selecting the partition column :
The column should have an index.
The column should be numeric or a date-column.
If the column is of string-type, ensure the bucket size is not too low for a distinct value.
Example : If you have to choose between city and person_name, select city as partition column, as person_name is highly unique.
