Carl Yeksigian updated CASSANDRA-11575:
---------------------------------------
Attachment: 11575.tgz
I've attached a simple CDC daemon for running testing outside of Cassandra.
To run it:
- Specify the Cassandra cdc_raw directory:
{{-Dcassandra.cdc_raw=/etc/cassandra/data/cdc_raw}}
- Specify the Cassandra commitlog directory:
{{-Dcassandra.commitlog=/etc/cassandra/data/commitlog}}
- Local Cassandra running to pull the schema from
Dependency is on a 3.8-SNAPSHOT cassandra, so running {{ant publish}} in the
cassandra directory will put the necessary jars into Maven.

> There are currently no dtests for the new cdc feature. We should have some,
> at least to ensure that the cdc files have a lifecycle that makes sense, and
> make sure that things like a continually cleaning daemon and a lazy daemon
> have the properties we expect; for this, we don't need to actually process
> the files, but make sure they fit the characteristics we expect from them. A
> more complex daemon would need to be written in Java.
> I already hit a problem where if the cdc is over capacity, the cdc properly
> throws the WTE, but it will not reset after the overflow directory is
> undersize again. It is supposed to correct the size within 250ms and allow
> more writes.
