Hi All,
I am pretty much new to HANA In-memory database. As far as my understanding goes to the architectural approach of HANA is
-it uses ETL/Log/Trigger based methods to fetch the data from a persistence storage to its own database.
a.) My question is, whatever database modification being done to the present in-memory database will need to be updated back to the persistence layer, then by which process it is being performed??
b.) If there is any conflict between the row-based/column based tables, how it is going to store from one approach to another, while storing it back to the persistence storage?
