--------------------------------------------
Summary: 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
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
