We have been exploring IoT specific C* schema design over the past few
months. We wanted to share the benchmarking results with the wider
community for a) bringing rigor to the discussion, and b) starting a
discussion for better design.
First the use-case: We have time-series of data from devices
Approach (4) or (5) are what I would go for - they are (as your results
show) basically identical as the composite partition key gets converted
into a single hash.
Looking at your doc, I think the issue is you are using < operators on the
day field. As Cassandra doesn’t natively do range queries o
What is the value returned from Charset.defaultCharset() on both systems?

Hi
I had to decommission one dc , now while adding bacl the same nodes ( i
used nodetool decommission) they both get added fine and i also see them im
nodetool status but i am unable to login in them .gives invalid mwtadat
error, i ran repair and later cleanup as well.
Any ideas?
Can you post the stack trace and you're version of Cassandra?

Hi,
I am trying to craft a deployment strategy for deploying and maintaining a
C* cluster. I was wondering if there are actual production deployments of
C* using K8s as the orchestration layer.
I have been given the impression that K8s managing a C* cluster can be a
recipe for disaster, especiall
