Hi... A few little questions about ZODB and ZCatalog... 1. I have a new Zope database (= 2.5 Mo). After adding a single PDF file of 3.5 Mo, the database is nearly 10 Mo huge !! Is required space into ZODB "reserved" by big blocks, or may the ZODB's size increase twice as the size of files which are stored into it ?? 2. After adding a few PDF files of nearly 3 Mo, stored as "ExternalFiles" (which means that only metadatas are stored into ZODB), and indexing them into a ZCatalog with TextIndexNG (my ExternalFiles provide a PrincipiaSearchSource method with the help of "pdftotext"), the size of the ZODB is 19 Mo. Does it means that full text indexing is using as much space as the document itself (but I'm starting with an empty ZCatalog) ?? 3. I'd like my products instances to be indexed automatically, as soon as they are created or modified. But as indexing seems to be quite long with big files, is it possible to index these documents in the background, so that the user does not have to wait until indexation is finished... 4. Does anyone have any experience with ZODB files bigger than 2 Giga-bytes on Linux. If so, how long does it take to pack ??
