Totally depends on the load balancing policy of your driver, your data model,
consistently level and you’re replication factor. The default token aware
policy for the DataStax java driver up to 2.1.4 and 2.0.9 would largely behave
this way if you combined it with a hot partition, and all other l

Ahmed,
Just using text and serializing as Json is the easy way and a common approach.
However, this list is for Cassandra commiter discussion, please be so kind as
to use the regular user list for data modeling questions or for any future
responses to this email thread.
Regards,
Ryan Svihla
leading to
this situation, can I suggest you respond on the user list with the following:
- Keyspace (RF especially), data center and table configuration.
- Any errors in the logs on the Cassandra nodes.
Regards,
Ryan Svihla

Corry,
This is the Cassandra developer mailing list aimed at contributors to the
Cassandra code base (not all of whom work for DataStax for example). Can I
suggest you contact DataStax and ask the same question?

I’d just contact sa...@datastax.com instead.

Kedar,
I recommend asking the user list u...@cassandra.apache.org this list is for the
development of cassandra and you're more likely to find someone on the user
list who may have hit this issue.
Curious issue though I haven't seen that myself.

Lokesh,
The modeling will change a bit depending on your queries, the rate of update
and your tooling (Spring-data-cassandra makes a mess of updating collections
for example). I suggest asking the Cassandra users mailing list for help since
this list is for development OF Cassandra.

Different DI frameworks have different initialization costs, even inside of
spring even depending on how you wire up dependencies (did it use autowire
with reflection, parse a giant XML of explicit dependencies, etc).
To back this assertion up for awhile in that community benching different

The standard reasoning for unit tests is specificity of errors. Well
written tests suites tell you where you screwed up exactly just by the
success and failure pattern, often cutting down the need for a debugger.

Token awareness has no effect on that fact.

Just noticed you'd sent this to the dev list, this is a question for only
the user list, and please do not send questions of this type to the
developer list.
