> I am looking into collectDelta method in DocBuilder.java and I noticed that
> to determine the deltaRemoveSet it currently loops through the whole
> deltaSet for each deleted row.
> Does anyone else agree with the fact that this is quite inefficient?
> For delta-imports with a large deltaSet and deletedSet I found a
> considerable improvement in speed if we just save all deleted keys in a set.
> Then we just have to loop through the deltaSet once to determine which rows
> should be removed by checking if the deleted key set contains the delta row
> key.
