------------------------------------------------------------------
I am very slow to understand the merge code... this so far handles the simple
path correctly but doesn't commit. It seems like the final MoveTask doesn't do
anything table-related due to having a LFD. I was expecting the original
MoveTask to still execute and load the table. Will continue looking next week.
Also it seems like explain query creates a write ID, which I probably won't
fix, merge with ACID will resolve that.
