I think this note in the partition key section is what you might be
looking for?
"Note that a table always has a partition key, and that if the table has
no clustering columns, then every partition of that table is only

Hi all,
I'm trying to understand the scenario when no clustering key is specified
in a table definition.
If a table has only a partition key and no clustering key, what order the
rows under the same partition are stored in? Is it even allowed to have
multiple rows under the same partition when

Regarding cassandra-stress, make sure that you initiate load outside of

How do I tell if compaction has completed?
I will add more iterations/time to the test.
Thank you

Pls
I’m confused about read vs write performance. I was expecting to see higher
write than read perf. I’m seeing the opposite by nearly 2X
Please help. Am I doing/configuring something wrong or do I have the wrong
expectations. I am very new to Cassandra. And this is not using Datastax. .
Hi Petrus, thanks for the feedback.
I couldn't found the percent repaired in nodetool info, C* version is
2.1.8, maybe it's something newer than that?
I'm analyzing this thread about num_token.
Compaction is "compaction_throughput_mb_per_sec: 16", I don't get pending
compactions in Opscenter.
We are using Cassandra 3.x version..
Recently, our production database is going through some instability issues. One
of our node is keep going down from every 2 days up to a few of times a day.
The node is down due to JVM out of memory. According to my investigation, I
suspect that this might
No, any node can be seed node. But to start the cluster and nodes addition you
need some node as seed node. Make sure to include at least one node from each
DC as seed. DO NOT make all nodes as seed.

Hello,
Can you please comment if first node in a cluster must be a seed node. Is it
mandatory or not? How will it behave

Increasing RF will result in nodes that previously didn't have a replica of
the data now being responsible for it. This means that a repair is required
after increasing the RF.
Until the repair completes you will suffer from inconsistencies in data.
For example, in a 3 node cluster with RF 2,
