What's the simplest way to get a dump of all memcached keys into a file?

Question

This is from just a single memcached server with around 20M keys (no expiry) and around 2G of data.

What\'s the easiest way to get a dump of all the key/value pairs

Answer 1

I used this bash script

#!/bin/sh
MESSAGE=`memdump --servers="127.0.0.1"`
while read -r line; do
    echo $line
    VALUE=`echo "get $line" | nc 127.0.0.1 11211`
    echo $VALUE
done <<< "$MESSAGE"

just replace IP / port if necessary
