Hi Benoit,

Thanks for pointing this out.

Yes, it will be carbon 1 preaggregate datamap. The MV implementation in
CarbonData will check whether the MV is an aggregation on single table, if
yes, it will be "always in sync" (will automatically trigger load to MV
table after loading the main table).

But if the MV involved multiple table join, it need to be manually rebuild.

Regards,
Jacky
