Re: Adding new DC

I wouldn't use either of the steps you outlined. Neither of them are correct. Follow the procedure documented here instead -- https://docs.datastax.com/en/cassandra-oss/3.x/cassandra/operations/opsAddDCToCluster.html. Cheers!

Adding new DC

Hi Which of the below approaches should be followed to add a new DC to an existing DC - Approach 1- 1. Create a new DC say DC2 of say 3 nodes while booting the first node as seed=true and subsequently using it as seed for the remaining two nodes. 2. Now restart all the 3 nodes while

Hello, We have run into a very interesting issue and maybe some of you have encountered it or just have an idea where to look. We are working towards adding new dcs into our cluster, here's the current topology: DC1 - 18 nodes DC2 - 18 nodes DC3 - 18 nodes DC4 - 18 nodes DC5 - 18 nodes

Re: Adding new DC with different version of Cassandra

I agree with Jeff here: It's not recommended to do that but it should be still fine :). Something that might be slightly safer (even though 3.11.0 is buggy as mentioned above...) could be to add a 3.11.0 cluster. Do the streaming with 3.11.0, upgrade the new DC only, switch clients over,

Adding new DC with different version of Cassandra

Hello All, We have datastax Cassandra cluster which uses 3.11.0 and we want to add new DC with apache Cassandra 3.11.3. we tried doing the same and data got streamed to new DC. Since we are able to stream data any other issues we need to consider. Is it because of same type of sstables used in
