----------------------------------
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.
