Thanks, I didn't know this interesting project.

This actord seems to focus on performance.
Its reliability depends on storage system like BDB, and data
partitioning is done by clients like memcache.

In our Kai, replication and partitioning are done by Kai nodes.
The number of replicas are automatically kept among Kai nodes, even if
some nodes are getting unavailable.
This mechanism leads to high scalability and reliability.

While targets are little bit different, it is very interesting for us.
