Zope Object Database store frontend.
|
||
|
|
|
||
|
|
shove's psuedo-URL for ZODB stores follows the form:
|
||
|
|
|
||
|
|
zodb:<path>
|
||
|
|
|
||
|
|
|
||
|
|
Where the path is a URL path to a ZODB FileStorage database. Alternatively, a
|
||
|
|
native pathname to a ZODB database can be passed as the 'engine' argument.
