riak_kv_memory_backend in production

2013-07-18 Thread kpandey
Are there known production installation of riak that uses riak_kv_memory_backend. We have a need to store transient data just in memory ( never hitting persistent store). I'm testing riak on aws with 3 node cluster and looks good so far. Just wanted to find out what kind of setup people are usin

Counting total items in a backend store with TTL

2013-07-22 Thread kpandey
All, This is kind of like the last thorn before moving with riak implementation for me. My use case for now is storing 1) transient payload in memory backend with ttl 2) storing something similar to user sessions in bitcask with ttl. Since the backend stores are ttl, I need to be able to cou
