Hi everyone,
I am trying to limit the length of a data export induced by the exportData() API call.
I have a Mashup where the underlying dataset can be downloaded via a button on the website.
To achieve this I create a table object via a .visualization.create() call and then I download the data behind this table via the exportData() function.
However I want to limit the length of the download. E.g. If the table actually has 10000 rows I only want to provide the first 500 for download.
As of now I create the whole download with all rows included and then throw away the rows that I don't want to show. This is a messy workaround I would like to avoid and also hurts the performance as the preparation of large datasets takes quite some time.
So I would like to know if there is a possibility to limit the dataset before downloading or if it is possible to modify the exportData function to only return a certain amount of rows.
Has anyone some experience with this?
Thanks and kind regards,
Marco
