Suppose I have a SuperColumn CF where one of the SuperColumns in each row is being treated as a list (e.g. keys only, values are just empty). In this list, values will only ever be added; deletion never occurs. If I have two processes simultaneously add values to this list (on different nodes, whatever), is that guaranteed to be safe from race conditions? The timestamp is on the actual entries in the SuperColumn, not on the row that contains those entries, right? Or am I wrong, and the last update to the row will overwrite a previous update to the row?
Also, in a scheme like this, is there a limit on the number of entries I can have in my "list"? I know that compaction normally needs to read an entire row into RAM in order to compact it. Does this also apply to SuperColumn columns?
