Dynamic file writes generate 1 set of files (shards) for every pane firing of every window of every destination. File naming policy is required to produce different names for every combination of (destination, shard index, window, pane) so you never have to append or overwrite. A new element arriving for a destination after something for that destination has already been written will simply be in the next pane, or in a different window.
