> Project: Causeway
> Issue Type: Improvement
> Components: Core

> Priority: Major
> Fix For: 3.4.0

>
> We are using POI's XSSFWorkbook for writing tabular data to XLSX. However,
> this Workbook implementation is not optimized for writing large files, as the
> entire XML model is held in memory.
> It is recommended to use POI's SXSSFWorkbook instead, which is optimized for
> writing streams of data and hence uses less memory.
