Hi @lindsay_knowcode & @chris.williamson1996 ,
You can try to create simple data type with less columns and do some workflow as bulk.
Example :
Create same table called “Sample 1” with columns of c1, c2 & c3. add more number of records upto 1000 and do some actions via workflow with iteration.
Same thing, you can add another data type with more number of columns with with more values and do the same workflow action as bulk.
Example:
Create same table called “Sample 2” with columns of c1, c2, c3,… c20. add more number of records upto 1000 and do some actions via workflow with iteration.
You can see the difference from above both.
I have got this info by doing some research in the generating reporting from the database tables.
Note: Its all about your records Weight/Size.
