You can create unlimited number of rows in baserow aswell you can fetch as many row you need.
For example, if you have 456 rows in a single column named Name then you can fetch first 200 datas from page 1 and second 200 from page 2 and remaining from page 3 .
If your page is invalid then it will raise the event OnErrror with page invalid message.
You can use logic something like this to get all the rows from baserow.
Here, all the list of datas/rows of column name Name is stored in global list variable.
-----(Updated)----
No need of this if you are using version 3.1 or above.
