Caleb Rackliffe commented on CASSANDRA-18040:
---------------------------------------------
+1...both PRs LGTM
We had talked about two others items:
1.) Having a small number of built-in configurations (guessing {{trie}} /
{{skiplist}} or something similar) that are present even if not specifically
defined in the YAML.
2.) Cluster-wide (but still locally overridable) changes in DDL-space.
I know we had intended to make #2 a separate Jira, but will #1 be as well?
Thanks!
> 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
> Priority: Urgent
> Fix For: 4.1-rc, 4.x
>
>
> 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.
