To select one or more tables:
Select the Connection Name from the drop down menu.
Select the desired schema.
Select the checkboxes for all the tables that need to be validated.
Click on Add Selected at the bottom.
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.
