Connect to cassandra without the key space name

[Bhavesh Joshi]

Hi,

I am using the cassandra-driver 

to create a connection to the driver it is using 

const client = new cassandra.Client({ contactPoints: ['h1', 'h2'], keyspace: 'ks1' });

Is is possible to connect to it without key space ?

I want to check if the keyspace exist otherwise create it.

and also can I use an url in contactPoints instead of the ip?

like xyz.aws.abc.com

which is the url to cassandra on ec2 instance.

Hi,

You can create a Client instance without setting the keyspace.

You can create it afterwards and either, use fully qualified table names, ie: "ks1.table1" or switch keyspace:

client.connect()

  .then(() => client.execute("CREATE KEYSPACE IF NOT EXISTS ks1 ..."))

  .then(() => client.execute("USE ks1"))

  .then(() => /* from this moment on, your connections are using the ks1 keyspace */);

Also, you can use the host name instead of the IP address, the driver will resolve the IP internally.

Hope it helps,

Jorge
