The log mechanism Prof. Stonebraker prefers, command logging vs ARIES, almost all newer data stores use command logging w/checkpoints (i.e., redis, mongo) and ship changes to other nodes similarly.

After running a large production redis environment, having a large redo log makes startup/recovery painful. I'm not convinced command logging is the most efficient in all scenarios especially when doing counters where the command is more verbose than the resulting change.
