Hi everyone,
Is there anyone who is running Cassandra on K8s clusters. It would be great
if you can share your experience , the operator you are using and the
overall stability of stateful sets in Kubernetes

Hi,
Does repair in cassandra handles secondary indexes repair/rebuild?
Has someone observed this/ is there any documentation related to it.
Regards
Hi,
This looks good but when can the discrepancy in the index arise. Any
specific example?
Is there any documentation which says the index automatically
rebuilds/keeps itself up to date after updations and deletions. Also if
there anything specific to stratio-lucene-index.

Hi,
How frequently one should run nodetool rebuild_index and what's its impact
on performance in terms of iops,cpu utilisation etc.
Regards
range be redistributed and the node will get
the new token range.
Would the process be different for seed nodes?

Hi alain
Thanks for the response.
I'm using cassandra 3.10
nodetool status shows all the nodes up
No schema disaggrement
port 7000 is open

I have a 10 node C* cluster with 4-5 keyspaces.
I tried to perform nodetool repair one by one for each keyspace.
For some keyspaces the repair passed but for some it gave this error:

Hi,
Is it right to load test the cassandra cluster using stress tool with
default keyspace, keyspace1 and having columns type as blob?
Hi,
What is the best way to stress test the cassandra cluster with real life
workloads which is being followed currently?
Currently i am using cassandra stress-tool but it generated blob data /yaml
files provides the option to use custom keyspace.
But what are the different parameters values
What is the correct process to backup and restore in cassandra?
Should we do backup node by node like first schema backup from all the
nodes then all other stuff?
In restore the schema should be restored on one node or all the nodes
again?It will give Already Exists Exception but still what's the
Is there any use case where we need full repair and incremental repair will
not help?
Actually i am performing incremental repair regularly is there any need to
run full repair?
hi,
Would there be any difference in the performance of the stress tool if the
keyspaces being populated are of type :-
One is of default keyspace1 standard1 having columns of blob type
Second one is of mixed type (string,int,text)etc.
Please tell in terms of ops/sec.
Hi,
Does using lucene index affects the performance of the read/write in
cassandra.
How heavy is the operation of creating a lucene index on a table with some
GB's of data?
You replace it with a new node and bootstraping happens.The new node
receives data from other two nodes.
Rest depends on the scenerio u are asking for.

So when i give a read only access to a user in jmxremote.access: ,they can
still run all the nodetool commands.Why is this so?

If Size Tiered Compaction Strategy is used, then on performing manual
compaction would there be always *1 sstable* at last irrespective of the
size?
Also would there be 2 sstables if repair has been performed?
Hi, there isn't a compaction task feature in
mesosphere/dcos-cassandra-service like repair and cleanup.
Is anybody working on it or is there any plan to add in later releases?
Regards
Is it helpful to run nodetool compaction in cassandra?
or automatic compaction is just fine.

Suppose I have a cassandra cluster with the data that is skewed such that
one node have 40% more data than other nodes.Since while creating the
cassandra the tokens were distributed uniformly.
Now to make the data uniform I have to recalculate the tokens and assign
them to nodes in the cluster.
. Then run repair and cleanup.
The question is How to recalculate the tokens and assign them to
nodes(Keeping cost ,distance between nodes and data movement in mind)

Hi,
I am performing repair on cassandra cluster.
After getting repair status as successful, How to figure out if it is
successful actually?
Is there any way to test it?
Hi everyone,
I'm new to cassandra.I was checking the nodetool repair command. I ran the
command and got success but I am not able to figure out how to check repair
has actually happened or not?
It would be a great help if somebody can suggest a way to do that in terms
of data check etc.
