Thank you Jürgen,
The default consistency in the library in already ONE. I tried setting it
anyways but it made no difference. Hopefully it is a configuration issue,
that would be very good news!!
Do you have any past/present experience with large counter tables?

Hi Alain,
Thank you for your reply. I have run the same test but writing into a
non-counter table equivalent to the counter one. The rate in this case is
around 160k writes/second. I am not sure if I should be expecting much more
in a 3 nodes cluster. In terms of I/O is not much really and the sys
Hi Javier,
The only bottleneck in the writes as far as I understand it is the commit

Sadly this is somewhat wrong, specially in your case. CPU, network limits
can be reached, and other issues, can happen. Plus in your case, using
counters, there is way more things involved.

As far as I have seen, you have not configured outbound consistency which
defaults to Local_Quorum. Try with ONE. Then there might still be a
configurstion issue. Concurrent compactors maybe or ressource contention on cpu
with the Test Code.

Hi again,
Two more thoughts with respect to my question:
- I have configured all 3 nodes to act as seeds but I don't think this
affects write performance.
- The hints_directory and the saved_caches_directory use the same drive as
the commitlog_directory. The data is in the other 7 drives as I expl
Hello everyone,
I have configured a Cassandra cluster with 3 nodes, however I am not
getting the write speed that I was expecting. I have tested against a
counter table because it is the bottleneck of the system.
So with the system iddle I run the attached sample code (very simple async
writes wit
