Table has lots of data.
When I want to export data with the function “system.dataset.exportExcel”, there was an error : java heap space.
Yes, that function constructs the entire spreadsheet in memory, then writes to disk. You will have to raise your client memory allowance.
What Phil said. Also, we made a change in 8.0.15 that will decrease the amount of memory used if any cells have dates, so it might be worth your while to upgrade as well.
