Hi there,=


Under wha= t conditions Cassandra generates a tombstone?=C2=A0

Basically I have not even big table on cassandra (90M rows) in my code th= ere is no delete and I use prepared statements (but binding all necessary v= alues).

I'm aware that a tombstone gets create= d when:

1. You delete the row
2. You set= a column to null while previously it had a value
3. When you use= prepared statements and you don't bind all the values

Anything else that I should be aware of?
