> We need to considering the following attributes of WALKey:
> * The cluster ids
> * Table Name
> * write time (here we could use the latest of any batch)
> * seqNum
> As long as we preserve these we can rearrange the cells between WALEdits. Since seqNum is unique this will be a challenge. Currently it is not used, but we shouldn't design anything that prevents us guaranteeing better ordering guarantees using seqNum.
