>             Project: Cassandra
>          Issue Type: Task

>            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.
> Thanks
> Kishore
