Subject [jira] [Created] (CASSANDRA-14591) Throw exception if Columns serialized subset encode more columns than possible
Date Wed, 25 Jul 2018 16:04:00 GMT
Benedict created CASSANDRA-14591:
------------------------------------

             Summary: Throw exception if Columns serialized subset encode more columns than
possible
                 Key: CASSANDRA-14591
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14591
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Benedict
            Assignee: Benedict
             Fix For: 4.0, 3.0.x, 3.11.x


When deserializing a \{{Columns}} subset via bitset membership, it is trivial to add a modest
probability of detecting corruption, by simply testing that there are no higher bits set than
the candidate \{{Columns}} permits.  This would help mitigate secondary problems arising
from issues like CASSANDRA-14568.
