             Summary: Avoid schema mismatch problems on memtable API misconfiguration
                 Key: CASSANDRA-18040
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-18040
             Project: Cassandra
          Issue Type: Improvement
          Components: Cluster/Schema
            Reporter: Branimir Lambov
            Assignee: Branimir Lambov


The memtable API requires a definition of the memtable configuration to exist in {{{}cassandra.yaml{}}}. If that is not the case when a schema change is received from another node, this can cause the node to reject the schema change and behave incorrectly.

To fix this, a node should only fail to construct a memtable when it is validating {{CREATE}} or {{ALTER}} statements, but should fall back to default when it receives invalid configuration selections in the schema.
