Subject Are updates on map columns causing tombstones?
Date Mon, 11 Jul 2016 14:16:55 GMT

when I replace the content of a map-valued column (when I replace the complete map), will
this create tombstones for those map entries that are not present in the new map?

My expectation is 'yes', because the map is laid out as normal columns internally so keys
not in the new map should lead to a delete.

Is that correct?
