Project mention: FileOutputStream v. ByteArrayOutputStream: is there a noticeable difference in memory usage? | /r/javahelp | 2022-12-20
I'm using fastexcel to create the excel file, and I'm flushing it to the OutputStream after every row is written. Right now, I am using a FileOutputStream to write to disk. When the excel file is done being generated, I read it back in using InputStreamResource and stream the response. My thought process is that a ByteArrayOutputStream keeps everything in memory even if I'm flushing the excel file after every row, so I used the FileOutputStream. Does my logic track here? Or am I unnecessarily slowing things down with expensive filesystem IO?

HI,may i suggest you my open source library which manipulates excel files. It uses Apache POI, but tries to give out-of-the-box tools for the user. The project is still in a development phase where I haven't defined many features yet and I'm always looking for many suggestions. Anyone is free to contribute. If you might be interested, here is the link:https://github.com/MBenincasa/java-excel-utils
