"nodetool repair -dc"

Hi , I have a question regarding "nodetool repair -dc" option. recently we added multiple nodes to one DC center, we want to perform repair only on current DC. Here is my question. Do we need to perform "nodetool repair -dc" on all nodes belongs to that DC ? or only one node of that DC? thank

Replicated data size

Hi All, I have a unique requirement from my management. Here is the details of it *Quick idea about my environment:* we have multi-DC( 2 dc's) setup 10 nodes each. keyspace RF of 3 each. We need to know how much data replicated across data centers on per day basis. is there anyway to calcula

Local_serial >> Adding nodes

Hi All, We are having 2 DC setup each consists of 20 odd nodes and recently we decided to add 6 more nodes to DC1. We are using LWT's, application dirvers are configuared to use LOCAL_SERIAL. As we are adding multiple nodes at a time we used option "-Dcassandra.consistent.rangemovement=false" we

Hi , I have a question regarding token distribution in muti-dc setup. We are having multi-dc (DC1+DC2) setup with V-nodes enabled. How token ranges will be distributed in cluster ? Is complete cluster has completed one token range ? Or each DC has complete token range?
