I've updated to 0.9.2 from pre-apache version 0.9.0.1 (which broke my Cassandra
bolt implemented using this code :

According to some posts, this is due to netty conflict. Could anyone please
suggest me an alternative
did you tried [1]https://github.com/ptgoetz/storm-cassandra.

Hi all,
I'm trying to learn how to use CassandraCounterBatchingBolt from storm-contrib
project on github.

InvalidTopologyException(msg:Topology name cannot contain any of the following:
#{. / : \\})
And I think it's because the Cassandra

Hi
I am actually looking into using CassandraCounterBatchingBolt but atm I'm not
sure how Cassandra handles these eventual consistency issues so I need to
research that. The reason I mention this issues is because I cannot find

Adrian,
See the email I just sent out to Laurent.
We have the exact same use case, and we are evaluating the use of lightweight
transactions (available in C* 2.0) to accomplish what you described without
falling into all the traps involved in a read-before-write counter update.

Hi Brian
Thanks for the reply. Currently using raw storm; doing ok without trident.
For me the use case is a simpler because I use fieldGrouping so all tuples w
the same ID will go to the same Cassandra bolt which means no other bolts
will update the values for the tuples read by current bolt
for the following scenario: I have tuples coming
to a cassandra bolt. The tuples are of this form: TupleData(String name,
Int count, Long time) Time field is unique per batch only but not overall
because some tuples may come in late but have the same name and time but
different count.
For example:
