Andrew Prudhomme commented on CASSANDRA-15210:
----------------------------------------------
For some more context, this is causing us problems in the case where a CDC
tracked table has large partitions. Since the streaming bootstrap is played
through the commit log, the stream will fail because of the (0.5 * commit log)
mutation size limit. This issue means that streaming will fail even when CDC is
disabled at the node level.
> Streaming with CDC does not honor cdc_enabled

> Key: CASSANDRA-15210
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15210
> Project: Cassandra
> Issue Type: Bug
> Components: Consistency/Streaming, Feature/Change Data Capture
> Reporter: Andrew Prudhomme
> Assignee: Andrew Prudhomme
> Priority: Normal
>
> When SSTables are streamed for a CDC enabled table, the updates are processed
> through the write path to ensure they are made available through the commit
> log. However, currently only the CDC state of the table is checked. Since CDC
> is enabled at both the node and table level, a node with CDC disabled (with
> cdc_enabled: false) will unnecessarily send updates through the write path if
> CDC is enabled on the table. This seems like an oversight.
> I'd imagine the fix would be something like
>
> {code:java}
> - hasCDC = cfs.metadata.params.cdc;
> + hasCDC = cfs.metadata.params.cdc &&
> DatabaseDescriptor.isCDCEnabled();{code}
> in
> org.apache.cassandra.db.streaming.CassandraStreamReceiver (4)
> org.apache.cassandra.streaming.StreamReceiveTask (3.11)
