This is an experimental storage driver where changed data is
appended. Data is simply written as key = value
pairs to
the end of the file. This allows changes to individual keys to be
written without needing to write out the entire object again, but reads
would grow gradually larger as it still needs to read old overwritten
keys. This may be suitable for e.g. rosters where individual contacts
are changed at a time. In theory, this could also allow rolling back
changes.
Requires 0.10
