Description Daniel Berrange 2003-11-04 05:49:43 EST
Description of problem:

All common JDBC drivers provide APIs for streaming of LOBs in & out of
the DB. These APIs, however, are not exposed/used by persistence, so
applications have to pull the entire LOB into memory when
reading/writing. This is not at all good for scalability of
applications using LOBs, such as CMS images / file attachments / Doc
Manager. A mere 10 users downloading 35 MB files will use up at *best*
350 MB, potentially some multiple of this amount if the byte[] are
copied in memory ever.
