<![CDATA[Trying to output large xlsx files]]>Hi,
We have been trying to find a solution that would let us output a xlsx file with multiple tabs and sometimes approaching 1M rows on a tab or 2. We currently can reliable get output up to ~400k rows using the xlsx recipe and fetching the data as a large json blob from sql.
I have been trying to rework this to enable sql pagination and one of the builtin helpers to work with the paginated data, then flush the before in a before render function. So far I have been unsuccessful due to different errors. RIght now using an htmltoxlsx recipe the helper (htmlToXlsxEachRows) doesn't seem t take an async anonymous function that would paginate over the data. It appears that the function is never called. The synchronous function that returns the anon function is called.

I am open to any suggestions about how to make this work. It seems all of the pieces are present, just not talking to each other to make it h appen.
