[jira] [Commented] (CASSANDRA-4791) When a node bootstrap in a multi-datacenter environment it should try to get data only from local nodes

Thom Valley commented on CASSANDRA-4791:
----------------------------------------

We are seeing bootstrapping in our 5 DC configuration frequently bootstrapping nodes from some of the longest distance alternate DCs.

Using GPFS with appropriate DCs defined.

Almost seems like random selection.

> When a node bootstraps, in a multi-datacenter environment, currently it is streaming data from any node available. But, to cut down the intra datacenter traffic, it should first try to stream data within the same datacenter or there should be a flag to explicitly limit it to stream data from its own data center.
