Cassandra 3.0.20 ETA?

[Steinmaurer, Thomas]

Hello,

as we are periodically hit in production by the following memory leak with 
3.0.18: https://issues.apache.org/jira/browse/CASSANDRA-15400

Is there any ETA for 3.0.20?

Thanks,
Thomas

Re: Returning data to the client after an INSERT

[Nivia Q.]

 Hello,
I am using Cassandra for academic purposes (trying to implement a consistency 
model using Cassandra as baseline). By now, I just would like to return some 
data in the form of a "result set" to the client after an INSERT operation.I 
only have changed the StorageProxy.mutate() method to return my ResultMessage 
object and ModificationStatement.executeWithoutCondition(), which calls 
mutate() to reflect the change.
However, now every time the client does an INSERT operation (clash or the 
python API ), a WriteTimeoutException is thrown by 
AbstractWriteResponseHandler.get(). Is there something I am missing? Is there 
any documentation about Cassandra's internal modules?

Thanks a lot,
Nivia  

Re: Can we upgrade Guava to the same version as master on 3.11 branch?

Russell,

That's great to hear. Then I'll wait for Cassandra 4 release for now.
In the meantime, I found an outdated dependency in Cassandra. Ticketed
