M7 allows the columns to be declared inmemory

Is there a impact , if I do

a) Huge number of deletes
b) Huge number of updates

Is there a case, where there can be data loss.

I want to understand, if inmemory columns have suitability for scenarios involving huge updates and delets

Cassandra provides similar functionality, but deletes are not considered (and remain in memory for 10 days, I guess)
