    public abstract class AColGroupOffset
    extends APreAgg
    Base class for column groups encoded with various types of bitmap encoding. NOTES: * OLE: separate storage segment length and bitmaps led to a 30% improvement but not applied because more difficult to support both data layouts at the same time (distributed/local as well as w/ and w/o low-level opt)
