Vinoth Chandar commented on HUDI-7665:
--------------------------------------
One consideration for TT queries is, even with compaction, the older log files
will be needed for TT queries.. So the reader has to be able to build file
slices correctly with log files named both ways... (base vs delta commit
difference)
> Rolling upgrade to table version 8
