Ok.
DataStax , Startio are required mesos, hadoop yarn other third party to
get spark cluster HA.
What in case of calliope?
Is it sufficient to have cassandra + calliope + spark to be able process
aggregations?
In my case we have quite a lot of data so doing aggregation only in memory

Interesting things actually:
We have hadoop in our eco system. It has single point of failure and I
am not sure about inter data center replication.
Plan is to use cassandra - no single point of failure , there is data
center replication.
For aggregation/transformation using SPARK. BUT storm r

Great stuff Paco.
Thanks for sharing.
Couple of questions:
Is it required additional installation to be HA like apache mesos?
Are you supporting PySpark?
How stable /ready for production ?
Thanks
Oleg.

Hi ,
I try to evaluate different option of spark + cassandra and I have couple
of questions:
My aim is to use cassandra+spark without hadoop:
1) Is it possible to use only cassandra as input/output parameter for
PySpark?
2) In case I'll use Spark (java,scala) is it possible to use only
cass
Hi All.
Is multi datacenter replication capability available in community
addition?
If yes can someone share the experience how stable is it and where can I
read the best practice of it?
Thanks
Oleg.
Hi ,
Where can I find the document with best practices about sizing for
cassandra deployment?
We have 1000 writes / reads per second. record size 1k.
Questions:
1) how many machines do we need?
2) how many ram ,disc size / type?
3) What should be network?
I understand that hardware
