Hi, I would be appreciative if you could help with below questions.
I have two question on Modify keyword with respect to Cassandra(No SQL database). 1) Whenever we grant MODIFY permissions to Cassandra users, for example: GRANT MODIFY ON table1 TO User1; Then all four: Insert, Update, Delete and Truncate permissions are granted automatically. But out of the four I do not want to give Truncate permission because I do not want a user to mistakenly truncate a table. I tried giving individual permissions of Insert ,Update and delete but this way it does not work. Only the Modify keyword works. Is there a way I can grant only Insert, Update and Delete to users in Cassandra. 2) I also have another question regarding Modify. Why is it mandatory to give MODIFY permission explicitly to a Cassandra Materialized View even when related table already has MODIFY permission? Whenever a table in Cassandra is modified (data updated/deleted/inserted), the related materialized View(MV) is updated automatically. Why is it necessary to give explicit MODIFY permission to MV (Materialized Views) as well in order to execute a Insert/Update/Delete on the related table? Further-more the contradictory thing here is that a Modify command (Insert/Update/delete) cannot be executed altogether on MVs. So below CQL will fail even if the user has Modify access on MV - "delete from materializedView1 where id =10" Another issue is that whenever a new MV is created on the same table, then the table Modify will go for a toss, if Modify is not given/missed on the New MV.
