Summary: Cassandra reapair process in Low Bandwidth Network Key: CASSANDRA-13870 URL: https://issues.apache.org/jira/browse/CASSANDRA-13870 Project: Cassandra Issue Type: Task Reporter: Kishore Mohapatra Priority: Trivial Hi, we have a cassandra cluster with 7 nodes each in 3 datacenters. Network bandwidth between DC1 and DC2 is very good (10Gbit/s) and a dedicated one. However network pipe between DC1 and DC3 and between Dc2 and DC3 is very poor and has only 100 MBit/s and also goes thru VPN network. Each node contains about 100 Gb of data and has a RF of 3. Whenever we run the repair, it fails with streaming errors and never completes. I could repair either just in the local dc or just the first two DCs. Can not repair DC3 when i combine with the other two DCs. So how can i succesfully repair the keyspace in these kind of environments ? I see that there is a parameter to throttle the inter-dc stream thruput, which default to 200 MBit/s. So what is the minimum threshold that i could set it to without affecting the cluster ? Is there any other way to work in these kind of envornments ? I will appreciate your feedback and help on this.
