Hi Guys, 

Have a couple of questions regarding the connections to cassandra,

1. What are the recommended number of connections per cassandra node? 

Depends on hardware. 

2. Is it a good idea to create coordinator nodes(with `num_token: 0`) and whitelisting only those hosts from client side? so that I can isolate main worker don't need to work on connection threads 

Defeats the purpose of having a masterless system. 

3. does the request time on client side include connect time? 

Who is measuring? 


4. Is there any hard limit on number of connections that can be set on cassandra?
