Summary: CEP-21 Dereference TableMetadata in simple partition
builder
Key: CASSANDRA-18418
URL: https://issues.apache.org/jira/browse/CASSANDRA-18418
Project: Cassandra
Issue Type: Task
Reporter: Marcus Eriksson
In some places we retain static {{TableMetadata}} instances and use them to
construct a {{PartitionUpdate}}. For instance, TraceKeyspace contains Sessions
& Events static members which are created at startup when the current epoch is
Epoch.EMPTY. These are later used to construct mutations when tracing is
enabled and when the mutations are serialised and sent between replica &
coordinator the epoch comparisons in PartitionUpdate deserializer trigger an
IncompatibleSchemaException. Ultimately we should not expose static
{{TableMetadata}} instances in this way.
