nodetool setstreamthroughput
Where is the cassandra.yaml
file?
The location of the cassandra.yaml
file depends on the type of installation:
Installation Type | Location |
---|---|
Package installations + Installer-Services installations |
|
Tarball installations + Installer-No Services installations |
|
Sets the throughput capacity in megabits per second (Mb/s) for outbound streaming in the system.
Overwrites the stream_throughput_outbound_megabits_per_sec
setting in cassandra.yaml
.
If inter_dc_stream_throughput_outbound_megabits_per_sec
is set, since it is a subset of total throughput, its value should be less than or equal to stream_throughput_outbound_megabits_per_sec
.
