I was reading the docs here: https://docs.datastax.com/en/archived/cql/3.1/cql/cql_using/use_expire_c.html <https://docs.datastax.com/en/archived/cql/3.1/cql/cql_using/use_expire_c.html>
It says "Expired data is marked with a tombstone after on the next read on the read path” - is this correct? My understanding of TTLs is that the expiry is written at write time and then the data is compacted out when it expires. It says here when you read the data, it generates a tombstone? Is this correct or are DataStax docs wrong? Thanks.
