论——memcached真的有工具可以dump出所有key嘛？

Using stats items and stats cachedump. You can list the keys stored in Memcached and infer their memory usage. Step 1: Identify Item Slabs . Run the following command using telnet or nc:

I know I can get all keys using some telnet commands (e.g., telnet localhost 11211; stats items; stats cachedump ), but it’s not clear to me how to automate this robustly. EDIT: Here’s what I

2）stats cachedump {slab_id} {limit_num} 获取slab下的key信息 stats cachedump 1 5 ITEM seller_shop_im_phone_122 [1 b; 1513935640 s] # key名称 ITEM seller_shop_im_phone_11542

Loop over each slab ID and issue the ‘stats cachedump $ID 0’ command and you’ll see all data. Now, if you don’t want to telnet each time, you can cheat a bit with this one-liner.

The dumping of the keys and their associated data relies on the undocumented command stats cachedump, which is needed to retrieve the keys. The command could be removed at anytime.

While @btilly is correct in saying that memcached does not do this natively, you can emulate it (quite efficiently) by maintaining an index of keys that share your prefix, allowing you to then
