使用easyexcel将大量数据写入excel，使用的是文件缓存还是先暂存在内存？ 分多次通过excelWriter.write(data, sheet0);写入excel，是可以解决内存占用过多的问题吗 找了很多文档，都没有明确的解释

Research direction
Examine the source code of ExcelWriter to understand how data is buffered during writes. Look for temporary file usage or in memory caching. Check if there is a configuration option for cache mode. Review test cases for large data writes.
