Question

Hi All,

I have a requirement; we need to store the document in S3, or at times we need to read the document (.xlsx) and present it in a grid format.

Sometimes, it contains 1 million rows. Is it possible to fetch the data in batches while reading the document from S3, or is there any other alternative approach to achieve this? without impact any performance.

Is this about the S3 API connectivity, or about how to display a multi-million row Excel file to a user?

1. Do you use the plugin or connected system or basic integrations? Did you check the typical API and Integrations file size limits?

2. An Excel is no database. And S3 is just a file storage. There is no way to read this in batches.

To fulfill this you need to download the document from S3 to Appian. Use some plugin to read/import the excel data (in batches, depending on plugin) then show on grid. As mentioned by others already, research on the file size restrictions as well as plugins to read about million rows from excel , and show in grid.
