Hi Aniket,
Its a well documented design, just want to know few points like
a. Format of the RowID and its datatype
b. Impact of this feature in select query since every time query process
has to exclude each deleted records and include corresponding updated
record, any optimization is considered in tackling the query performance
issue since one of the major highlights of carbon is performance.
Thanks,
Sujith
