comment NodeJs Cassandra driver is getting stuck
Also, have you tried with a simple query to narrow down the issue, something like client.execute('SELECT * FROM system.local', callback)

comment NodeJs Cassandra driver is getting stuck
From your code, connect() and execute() are going to be called in parallel, is that what you wanted? It looks like you are dealing with method calls like they were synchronous. In your case, console.log("Starting C* getting data"); will be called before the client is connected.

comment Datastax c# Cassandra throwing exception after update to 3.X
Could you post the schema of the table and the class that is failing. Have you check if you are using the expected type in the query (ie: Guid if the id is of uuid cql type)?. Another pointer: reuse the cluster instance across your application.

comment Datastax c# Cassandra throwing exception after update to 3.X
It looks like a driver issue, can you post the stack trace? Anyway, remember to use query markers instead of hardcoded parameters as adviced in the documentation: docs.datastax.com/en//developer/csharp-driver/3.0/csharp-driver/…

Are you using hardcoded parameters in the query or parameter placeholder?
