I am using cassandra dse 4.7, 3 node running cluster with one data center, now we are planning to add another data center with 3 nodes. I followed the steps mentioned in:
We have around 20GB of data on each node (total : 60GB).
The problem is when I run:
nodetool rebuild --old_datacenter_name on one of new node
it is very slow to sync data from cluster. I have already increased
getcompactionthroughput but still no luck.
Are there any other parameters I could tune for faster synchronisation of the data to a newly added node?
