[jira] [Resolved] (LUCENE-5678) Investigate to use FileoutputStream
instead of RandomAccessFile in FSIndexOutput
[ https://issues.apache.org/jira/browse/LUCENE-5678?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Uwe Schindler resolved LUCENE-5678.
-----------------------------------
Resolution: Fixed
Committed to trunk.
We might backport this to 4.x, once we removed deprecated seek() in IndexOutput. We can discuss this later, once this simplified/standardized code has proven to be as fast and stable.

> We no longer allow seeking in IndexOutput, so there is no need to use RandomAccessFile. We can change this with a < 1 KiB patch.
> Further improvements would be to merge this with OutputStreamIndexOutput, so we get many simplifications.
> There is also no reason anymore to separate DataOutput from IndexOutput. The only additional thing is IndexOutput#getFilePointer(), which is handled by an internal counter (does not use getFilePointer of the underlying RAF) and checksums.
