Hi Chan,
Instead of:
{storage_backend, riak_kv_memory_backend},
{memory_backend, [
{max_memory, 8192},
{ttl, 1}
]},
Try:
{multi_backend_default, <<"expiring_memory_backend">>},
{multi_backend, [
{<<"expiring_memory_backend">>, riak_kv_memory_backend, [
{max_memory, 8192}, %% 8GB
{ttl, 1}
]}
]},
Also, for future reference, the max_memory field is in MB per vnode, so your
current setting is 8GB per vnode. Unless you have a ridiculous amount of RAM,
you might want to reduce that setting a bit :)
Thanks,
Alex

Hi~!
I'm checking riak to use as a cache like memcached.
But I found some strange situation.
I set "ttl" like this to expire data, but failed.
---------------------------------------------
{riak_kv, [
...
{storage_backend, riak_kv_memory_backend},
{memory_backend, [
{max_memory, 8192},
{ttl, 1}
]},
...
]},
---------------------------------------------
TTL isn't supported on riak_kv_memory_backend?
I changed riak_kv_memory_backend to riak_kv_bitcask_backend, that's fine.
Thanks.
Chan.
