Could it be that the delete and insert have the same timestamp? Are you using batched queries maybe? In my current project a team experienced similar behavior during automated tests If you delete with T1 and insert with T1 the delete wins, which was the reason in our case. You might want to test this with client provided timestamps and make sure the insert has a T_insert > T_delete Jan > > Is it a bug on Cassandra or on Datastax driver? > Any suggestions? > > Tks
