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 & 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
