  == Why do my large attachments get truncated? ==

  Databases such as MySQL have a maximum size that can be stuffed in a
  given column.  You may need to change the column type for prop
  values to allow them to fit larger things.  The relevant columns are
  baz_propval.value and baz_cacheentry.value.  In MySQL, Blob columns
  can hold 64 kB, MediumBlob columns 16 MB, and LargeBlob columns 4
  GB.  You can modify the types directly in the database without
  making any code changes.  If you need more than that, you're doing
  it wrong.  Also, you'll exceed your
  [[http://sql.mit.edu/|sql.mit.edu]] quota.

  Note that attachments smaller than the maximum size will only take
  up the size they have; there is only a byte extra storage used up
  for each larger blob object, so erring on the size of large is not a
  bad plan.  But watch your quota, or you'll lose automatic backups.
