get all keys and values

[blumenkraft]

Hi,

Is it possible to get all keys and values from MemcacheDB?

you may use rget command, but because rget is not part of memcache
protocol, so you need patched client library.

It is handy for python, there is a memcache.py in distribution that
support rget.

Here's a sample script that uses rget to traversal MemcacheDB:

mc = memcache.Client(['127.0.0.1:21201'], debug=0)
start_key = "0"
item_list = []
item_list_slice = []
while True:
item_list_slice = mc.rget(start_key, "z", 1, 0, 100)
if item_list_slice == []:
break
else:
item_list += item_list_slice
start_key = item_list_slice[-1][0]
mc.disconnect_all()
