Re: [ZODB-Dev] Blobstorage shrinks only after the second pack operation - bug or feature?

I doubt either.

I used the default of the Zope 2 UI which is 0 (days). You didn't answer my question. I didn't ask how many days you packed to. I asked if you set pack-keep-old. I'm guessing from your response that you didn't. If you don't set pack-keep-old to false, then old blobs are kept around, just like the file-storage file, except that, rather than making copies, hard links are created. The second time you packed, the old links would be removed, freeing up the space taken by the old blobs.

I'm guessing from your response that you didn't. There is no such value exposed exposed in the Zope 2 database management control panel. It only offers the same packed-to value as it did ten years ago.
