From what I can see, when using Riak to update an object, I first need to load the object into PHP, then edit the object, then store the object back to the Riak database.
I was wondering if there is a way to update a bucket without pulling it into PHP first. That way, it would save on the network…

I'm trying to evaluate using Riak's Post-Commit Hooks to build a distributed, incremental MapReduce-based index, but was wondering which Riak nodes the Post-Commit Hooks actually run on. Are they run on the nodes the client used to put the commits, or on the primary nodes where the data is persisted…

I am using the erlang mode in Aquamacs.
The mode, by default, creates a new pane and buffer "*erlang*" when I hit C-C C-K to compile an erlang file. (as seen in the attached screen shot)
What is the easiest way to switch between these two panes?
I do not think "C-x b" is applicable in this case…
