> The nice thing is that binary_to_term seems perfectly happy reading a mix of

Just thinking that space may be at a premium for some users and enabling
compression could save them quite a bit of space depending on the data stored
in docs. Compressing attachments could be beneficial too, and for particular
use cases compression might increase read throughput due to needing less disk
reads. As Adam says, we need to measure it.
