Yes it is.
But it depends on what you want to select.
Cassandra does not have a complete query language like SQL in an RDBMS. You
need to design your data model to support the queries you wish to make.
Normally this means denormlising data so that queries are essentially reading
from a materi
i don't get it. Suppose i have a data model and i have million of rows and
suppose i want perform some select and some insert , it is not feasible to use
cassandra for those reasons?

You data load is fine.
It sounds like you will run into issues with the data model and functionality
of cassandra. "Standard Analysis" in the RDBMS sense of throwing any ad-hoc
query at the data and letting the query engine work it out is not possible
without using HIVE/PIG or some other query
make example of cases please?

That's for sure not much.
Your rdbms can probably hold the entire dataset in memory, and you can do
all kinds for queries that you want. Cassandra is for some very specific
use cases.
If you really need a cluster, have you thought about MySQL Cluster?

Standard analysis, display or aggregate some rows
or standard operations that i can do on a normal dbms

You provide zero information on what you are planning to do with the data.
Thus, your question is impossible to answer.

10 writes / second could even be done with every sql/nosql solution, even with
plain files.
So I think the storage choosen should be the one optimized for the queries you
wanna have.

It sounds like you would be fine doing what you propose.
