decommission),but this node hasn't updated its ring metadata yet. Adding
mutation to local batchlog to be replayed later.
I did nodetool decomission on one of the node.

field is appx 12~20 characters
Query :
1) How much data I can put in one partition ?
2) I want to read data from cassandra as
SELECT * from code where campaign_id_sub_partition = 'XXX-1';
Is reading whole partition at one time is feasible or shall I use
pagination ?
