Limitations with “Forminator free and wpDataTables Premium”.

Hi,
I read somewhere that there are limitations on the number of saved rows, but it is not very clear to me where these limitations are valid?
I am using the plugin “wpDataTables integration for Forminator Forms” with “Forminator free editon” and “wpDataTables Premium”.
Does the restriction I read about: “Those tables do not have a server-side option (this means that these tables can’t contain a large amount of data (no exact limit, but 2.000 – 3.000 rows is a good example)), and that they cannot be editable.” apply here or does it mean with other tables linked to other sources? This is not entirely clear to me.
Thank you in advance for specifying exactly what these limitations apply to.
Kind Regards.
