Query (which does not work) can be :
SELECT * from test_path where metadata CONTAINS {values: {'FOX'}, 'SOX'}} ;
OR
SELECT * from test_path where metadata CONTAINS {values: {'FOX'};

Hello,

Hi
We have a 2 Cluster Node with RF=2. We are planing to add a new node.
Should we change RF to 3 in the schema?
OR Just added a new node with the same RF=2?
Any other Best Practice that we need to take care?
Thanks

Does the nproc,nofile,memlock settings in
/etc/security/limits.d/cassandra.conf are set to optimum value ?
it's all default.
What is the consistency level ?
CL = Qurom
Is there any other way to export a table to CSV?

2. Is it related to driver?
Initially when I was trying 15MB and it was throwing the same Exception but
after that it started working.

Hi Ajay,
1. you should have at least 2 Seed nodes as it will help, Node1 (only one
seed node) is down.
2. Check you should be using internal ip address in listen_address and
rpc_address.

Should I first remove the node and then add a new node or Add new node and
