> > I remember that when DV is turned on, the returns are out of order, not sorted by primary key. > > Why is it out of order? IMO, it will sort by the primary keys in a single DataFile, and using the deletion-vector to mark its deleted row id. > > The mainly idea on this PR is to convert the TopN primary keys predicate into limit predicate when reading a single DataFile, then the compute engine (e.g. Apache Spark) will do the Global TopN. I see, for single data file, it is true. -- This is an automated message from the Apache Git Service.
