Subject [jira] Commented: (JCR-851) Handling of binary properties (streams) in QValue interface

Jukka Zitting commented on JCR-851:
-----------------------------------

The most usual (only?) reason for a client to create QValues is when the client wants to store
content in the repository. I would argue that in 99% of those cases the created QValue is
never read by the client.

As far as I can tell, this essentially requires a QValue implementation to preserve the whole
content of a stream, be it in memory or on disk.
> In particular (and unless I'm missing something), when importing large content into a
repository, this causes the whole data stream to be written twice. We really should try to
avoid that.
