Redis のメモリが足りなくなった時にどうやってチューニングしたか ref: http://qiita.com/eccyan/items/e8cc56948a00d6aad0aa
$ rdb -c memory dump.rdb > redis_memory.csv
# バイトサイズとキーの個数と単位バイトサイズを出す
$ cat redis_memory.csv | sed -E "1d" | sed -E 's/:[0-9]+(:|")/:{id}\1/g' | cut -d ',' -f 3,4 | awk -F ',' '{ sum[$1] += $2; count[$1] += 1 } END { for (key in sum) print key, sum[key], count[key], sum[key] /count[key] }' > redis_memory_status.csv
