Hi all,

Could someone explain with an example what's the difference between :

*riak_kv_cache_backend_max_ttl
and
**riak_kv_cache_backend_ttl

Does the value of riak_kv_backend_max_ttl is also in seconds?

Here's a snippet from the documentation found at
http://wiki.basho.com/Configuration-Files.html
*

   - *riak_kv_cache_backend*
   A backend that behaves as an LRU-with-timed-expiry cache
      - *riak_kv_cache_backend_memory*
      Maximum amount of memory to allocate, in megabytes (default: “100”)
      - *riak_kv_cache_backend_ttl*
      Amount by which to extend an object’s expiry lease on each access, in
      seconds (default: “600”)
      - *riak_kv_cache_backend_max_ttl*
      Maximum allowed lease time (default: “3600”)

Thanks!
