问题
I want to list all the keys stored in the memcached server.
I googled for the same, I got some python/php scripts that can list the same. I tested it but all went failed and none gave me full keys. I can see thousands of keys using telnet command
stats items
I used perl script that uses telnet to list keys, but that got failed too. I mean that script is listing keys but not all of them.
Do I need to reconfigure telnet ? Is there any other way ?
回答1:
memcache does not provide an api to exhaustively list all keys. "stats items" is as good as it gets to list the first 1M of keys. More info here: http://www.darkcoding.net/software/memcached-list-all-keys/
Not sure if that helps you but redis (which could be considered a superset of memcache) provides a more comprehensive API for key listing and searching. You might want to give it a try.

It you use python-memcached, and would like to export all the items in memcache server, I summerized two methods to the problem in this question: Export all keys and values from memcached with python-memcache
