Why did you choose java for the operator implementation when everybody
seems to use the go client (probably for greater functionalities) ?

Best practise is to use a dedicated DC for analytics separated from the hot
DC.

Aren't you using mesos Cassandra framework to manage your multiple clusters
? (Seen a presentation in cass summit)
What's wrong with your current mesos approach ?
I am also thinking it's better to split a large cluster into smallers
except if you also manage client layer that query cass and you can

Hi all,
Is there any way to trace user activity at the server level to see which
user is accessing which data ? Do you thin it would be simple to implement ?

The problem with adhoc queries on casssandra (with spark or not) is the
partition model of cassandra that needs to be respected to avoid full scan
queries (the link you mentioned explains all of them). With FiloDB, which
works on cassandra, you can pushdown predicates of the partition key and

I gave a try on spark+filodb and it's very interesting for ad-hoc queries

Or use graphframes (Spark) over cassandra to store separately a graph of
users and followers and next a table of tweet. You will be able to join
data between those 2 structures using spark.

Maybe a SMACK stack would be a better option for using spark with

I am looking for way to optimize large reads.
I have seen using SSD is a good option but out of budget, so I am looking
for a way to use some kind of tiering with few SSD caching hot data from
HDD.
I have identified two solutions and would like to get opinions from you and
