how to disable delete in replication Cassandra datastax
You can disable delete,insert and update using the built-in Cassandra security

CREATE USER test_user WITH PASSWORD xxxx NOSUPERUSER;
GRANT SELECT TO test_user ON my_table;


Unfortunately, it will also disable INSERT and UPDATE. Right now there is no way to disable only DELETE.

Indeed, even if you disable DELETE and allow INSERT &amp; UPDATE, it is still possible for the user to delete data, by just inserting null or updating with null values because inserting null == DELETE in CQL semantics
