Hello all,
I was trying to explore more about the custom payloads which was introduced
in protocol version v4. I could not get the actual use case using custom
payload. Can somebody shed some light on this? Appreciate your help:)
Thanks and regards,

Hello,
Is it wise and advisable to build multi cloud environment for Cassandra for
High Availability.
AWS as one datacenter and Azure as another datacenter.
If yes are there any challenges involved?
Thanks and regards,
Goutham.

True Bharath, there is no option to add a default value in Cassandra for a
column.

Kenneth,
I believe "static column" applies for one partition key. Correct me if my
understanding is wrong.

Hi,
We have a requirement to add constant value to all the rows for a
particular column, and we could not find any solution. Can anybody provide
standard procedure for the problem. Appreciate your help.

Hi,
As each partition key can hold up to 2 Billion rows, even then it is an
anti-pattern to have such huge data set for one partition key in our case
it is 300k rows only, but when trying to query for one particular key we
are getting timeout exception. If I use Spark to get the 300k rows for a
application.

Thank you very much Dor for the detailed information, yes that should be
the primary reason why we have to isolate from Cassandra.

Hi,
We have requirement of heavy data lifting and analytics requirement and
decided to go with Apache Spark. In the process we have come up with two
patterns
a. Apache Spark and Apache Cassandra co-located and shared on same nodes.
b. Apache Spark on one independent cluster and Apache Cassandra as
y unassigned and there’s no ETA.

Hi,
Does Apache Cassandra supports data at rest, because datastax Cassandra
supports it. Can anybody help me.

I would like to know how the Token Function works in Cassandra. In what
scenario it is best used. Secondly can a range query performed on token
function on a composite primary key. Any help is highly appreciated.

Hi,
We got a requirement to migrate only one keyspace data from one cluster to
other cluster. And we no longer need the old cluster anymore. Can you
suggest what are the best possible ways we can achieve it.
Regards
Goutham Reddy
Get the JARS from Cassandra lib folder and put it in your build path. Or
else use Pom.xml maven project to directly download from repository.
