How can I find the last access time of a redis key?

Question

In redis, two of the eviction policies, allkeys-lru and volatile-lru, evict keys based on access time. So, this information must exist somewhere. Is it possible for me to query the access time of a key? Or, better yet, page through a sorted list of keys based on access time?

Answer 1

Look at Object IDLETIME it gives time for which the object was idle

as guided by @Itamar Haber the way they disable some command is by using redis.conf

# It is also possible to completely kill a command by renaming it into
# an empty string:
#
rename-command FLUSHDB ""
rename-command FLUSHALL ""
rename-command DEBUG ""

As you are using Redis as a service on Heroku you have to have admin rights to do this Hope this helps!
