[jira] [Created] (TIKA-622) Switch from POIFSFileSystem to
NPOIFSFileSystem, for speed and memory improvements
Switch from POIFSFileSystem to NPOIFSFileSystem, for speed and memory improvements
----------------------------------------------------------------------------------
Key: TIKA-622
URL: https://issues.apache.org/jira/browse/TIKA-622
Project: Tika
Issue Type: Improvement
Components: parser
Reporter: Nick Burch
Assignee: Nick Burch
Priority: Minor
With POI 3.8 beta 1, there's an alternate OLE2 implementation NPOIFSFileSystem. From an API level, it's very similar to the existing POIFSFileSystem class, but internally it's lower memory and generally faster.
While NPOIFSFileSystem is currently read only (the write support has a couple of gaps), for Tika's needs that isn't an issue
We should therefore switch our uses of POIFSFileSystem to NPOIFSFileSystem to reduce memory and enhance speed.

Nick Burch updated TIKA-622:
----------------------------
Attachment: NPOIFS-3.8beta2.diff
The patch NPOIFS-3.8beta2.diff depends on the latest POI snapshot, so can't be applied until 3.8 beta 2 is out. However, it allows all unit tests to pass when using NPOIFS (and also includes TNEF which depends on 3.8 beta 2), so can be applied as soon as the new POI release is out
