LevelDB Database Store.
|
||
|
|
|
||
|
|
shove's psuedo-URL for LevelDB stores follows the form:
|
||
|
|
|
||
|
|
leveldb://<path>
|
||
|
|
|
||
|
|
Where <path> is a URL path to a LevelDB database. Alternatively, the native
|
||
|
|
pathname to a LevelDB database can be passed as the 'engine' parameter.
