Henry Saginor commented on OAK-8275:
------------------------------------
Hi [~reschke]
Some Java libraries require File or SeekableByteChannel
See for example
[https://commons.apache.org/proper/commons-compress/javadocs/api-1.18/org/apache/commons/compress/archivers/zip/ZipFile.html]
This is why I used Zip files as an example. But there are probably other use
cases as well. Applications built on top of OAK (at least those I know) create
temp files to overcome this limitation.
> Add NIO channel access to JCR binaries

> Key: OAK-8275
> URL: https://issues.apache.org/jira/browse/OAK-8275
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Reporter: Henry Saginor
> Priority: Major
>
> This is a follow up to the discussion started in OAK-8186. Currently JCR
> binaries can only be accessed via InputStream. This is inefficient. It can
> also be inadequate for some use cases. For example handling some Zip file
> formats like deflate64 requires random access.
> The proposal is to add API that returns SeekableByteChannel
> Here is the new API I am proposing -
