Subject [jira] [Commented] (TIKA-2963) Tika在抽取.xlsx类型的大文件时出现OOM错误
Date Fri, 11 Oct 2019 15:28:00 GMT

    [ https://issues.apache.org/jira/browse/TIKA-2963?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16949551#comment-16949551

Tilman Hausherr commented on TIKA-2963:

"For docx and pptx type files, Tika can configure the SAX parser to improve decimation performance.
However, Tika still has an OOM error when extracting large files of type .xlsx. I have not
found a solution from the official. I have attached my own code below. It is also a solution
based on SAX parser. The code can be adjusted according to the actual situation. Excellent,
there are many shortcomings, everyone criticizes and corrects, thank you"

I wonder what is meant with "decimation performance". After deleting single words, I suspect
it is extraction. So what she/he means that the current solution uses too much memory and
the proposed SAX based solution is better.

> 对于docx和pptx类型的文件,Tika可配置SAX解析器来提高抽取性能。但是Tika在抽取.xlsx类型的大文件时仍会出现OOM错误,我暂时没有从官方找到解决方案,下面附上自己的代码,也是基于SAX解析器的解决方案,代码可根据实际情况进行参数调优,多有不足之处,大家批评指正,谢谢
