Development discussions and code in progress
-
Jean-Daniel Cryans, put up 0.9.0 RC1 for vote on the dev mailing list and it passed. The Incubator PMC (IPMC) will also need to vote on it before it can officially be released.
-
Mike Percy is working on removing LocalConsensus which is currently used for single node Kudu deployments. We will instead use the Raft consensus implementation with a replication factor of 1. This is to simplify development since we need to maintain two consensus implementations. It will also provide a way to migrate from single node to multi-node deployments. See the discussion in this dev thread.

Zhen Zhang got a patch in for KUDU-1444 that adds resources usage monitoring to scanners in the C++ client. In the future this could be leveraged by systems like Impala to augment the query profiles.

Longer term efforts for 1.0 are making good progress. Dan Burkert added support in the C++ client for non-covering range partitioned tables, and David Alves has a few patches in for the Replay Cache.
