Hi all,
Yesterday I put up a new proposal on the http://dev.zope.org site that documents my vision of PersistentBlob. The main idea is the be able to mark blocks of strings (text or binary) content for storage in a file system as individual files. (Or blobs in a relation table.)
The two motivations for this are keeping a ZODB FileStorage small and exposing blocks of string content to external processes (i.e. full-text indexing).
Thanks for taking a look. John
Hi John! Have you had a look at the ExtFile Product (http://www.zope.org/Members/MacGregor/ExtFile)? It basically does all the things you want to achive with the PersistentBlob (i.e. storing files externally and making them accessible for external processes), except that it's not that deeply integrated into the Zope machinery and stores the files only in the file system and not in an RDBMS (which nevertheless could be implemented). Cheers, Gregor!
