    from 6453e85  Merge pull request #11333 from jhnmora000/master
     new 497cd03  Make BatchGroupAlsoByWindowViaIteratorsFn extend the ElementByteSizeObservableIterable so that size estimation is lazy
     new 573289a  Do not attempt to estimate sizes of group-by-key values behind a key; such iterables can have enormous sizes and size estimates would cause reading the data multiple times.  Furthermore, the size of the entire group-by-key collection is already known precisely at read time (and encoded into corresponding counters), which means the estimation is in fact not only expensive but redundant and unnecessary.
     new 0cd43d1  remove comments
     new 33091d2  Make BatchGroupAlsoByWindowViaIteratorsFn extend the ElementByteSizeObservableIterable so that size estimation is lazy
     new 62e4df7  revert changes to grouping shuffle reader and iterable like coder
     new fc180dd  fix merge conflicts
     new dd9ab00  remove obsolete class
     new 4d38e39  Merge pull request #11598 from tudorm/no-expensive-size-estimation-gbk
