Quick update re: dtests and off-heap memtables:
I’ve filed CASSANDRA-14056 (Many dtests fail with ConfigurationException:
offheap_objects are not available in 3.0 when OFFHEAP_MEMTABLES=“true”)
Looks like we’re gonna need to do some work to test this configuration and
right now it’s pretty brok
What you're wanting really isn't supported/available, but you could
probably extend cassandra to do this with some work.
Doing this at replication time is the wrong point, though - you want to do
it before the mutation is applied locally, so triggers are still the
closest to the right point as it
Looks like you’ve got this thread going on the user & dev ML. This list is the
dev one, and is meant for discussion of the Cassandra project. Would everyone
mind replying to the thread of the same name on the user list instead?

ok please find bellow an example:
Lets suppose that i have a cassandra cluster of 4 nodes / one DC /
replication factor = 4, So in this architecture i have on full copy of the
data on each node.
Imagine now that one node have been hacked and in some way with full access
to cqlsh session, if data

Trigger does not resolve my problem because it is not a format validation
issue but an integrity constraint ...
My purpose is to check data integrity before replication, by returning an
error and killing the service, so i am killing the node that is supposed to
replicate data after a write action
Going to hate myself for this, but check out the trigger interface.

Pay attention to the note that says the API is in beta and subject to
change. It's had that note for many years, which is
Hi,
You can't prevent the replication because if you manage to return a failure the
other node will keep trying to send the data. What would be more relevant is to
prevent the modification in the first place. You could try to implement a
custom trigger and load it in Cassandra:

1) There are a LOT of bugs in cassandra-3.0.9. Some of them are really bad,
you should definitely consider upgrading to 3.0.15.
2) The GC profile changed between 2.0 and 3.0. It may be that you're
generating a bit more garbage and causing GC pauses (especially likely
since you're using thrift), or
Hi,
I have some security constraint on a project, and i need to validate or
unvalidate changes made on a keyspace via cql or via an other ways before
replication.
for example in the case of multinode cluster with replication, if data was
changed locally using cqlsh, data will be replicated (that

Hi Alex,
It's still not visible... I don't think the mailing list supports image
attachments. Maybe you can create an issue on JIRA with the attachments?
