             Summary: Fix Result-Metadata Race Causing Corrupt SKIP_METADATA Row Decoding
                 Key: CASSJAVA-130
                 URL: https://issues.apache.org/jira/browse/CASSJAVA-130
             Project: Apache Cassandra Java driver
          Issue Type: Bug
          Components: Core
            Reporter: Yifan Cai
            Assignee: Yifan Cai


When a prepared statement's SKIP_METADATA response is decoded, the driver reads whatever column definitions are currently cached on the DefaultPreparedStatement, not what was in effect when that execution's request was encoded. A concurrent execution that triggers a CASSANDRA-10786 schema-change update to that shared cache can therefore cause an in-flight execution to decode its row bytes against the wrong column layout. This change snapshots the result metadata at encode time and threads it through decoding so each response is decoded against the metadata that was true when its request was built.
