Subject [jira] [Commented] (CASSANDRA-8708) inter_dc_stream_throughput_outbound_megabits_per_sec seems to default to 0 (unlimited)
Date Sun, 01 Feb 2015 04:45:34 GMT


Sean Thornton commented on CASSANDRA-8708:

Ideally if intra-dc was set below inter-dc, inter-dc would also be lowered.  Similarly, if
inter-dc was raised above intra-dc, intra-dc would also be raised.  After all, all traffic
starts as intra datacenter traffic.

Also would be nice to have inter_dc_stream_throuughput exposed via nodetool/jmx

> inter_dc_stream_throughput_outbound_megabits_per_sec was introduced in CASSANDRA-6596.
> There's some discussion in the ticket of the intention to link the default to whatever
stream_throughput_outbound_megabits_per_sec is set to.  
> However, it looks like it's just set to 0 - from /src/java/org/apache/cassandra/config/
> This is a bit of a pain - usually folks want to set the inter dc limits lower than the
base streaming figure.
