Please answer these questions before submitting your issue. Thanks!

What version of Cassandra are you using?

Scylla 4.1

What version of Gocql are you using?

latest

What did you do?

create new session

For monitoring and managing purpose it is useful to read from a node system table.
The system tables are node local so there should be a way to specify the host we want to open the session to.

for example something like:

options = &sessionOption{
    host: '192.168.1.2',
}
gocql.NewSession(cluster, options)

@amnonh Hi! It is possible to set custom HostFilter in ClusterConfig, which will limit the hosts that the client connects to. See also WhiteListHostFilter

Thanks @martin-sucha, maybe I'm using the wrong terminology, and it should be done on the session level per query.
The driver discovers the cluster topology, so for regular queries, it should choose the destination by itself.

There should be a way to choose the destination node for a specific query (I would rather not handle my own per-node connection)

It will be solved when #1793 is merged
