Dear Wiki user,

The "Streaming" page has been changed by JonathanEllis.

--------------------------------------------------

   1. The source copies the data in those ranges to sstable files in preparation for streaming.
 This is called anti-compaction (because compaction merges multiple sstable files into one,
and this does the opposite).
   1. The source sends the list of files to be streamed to the destination, followed by the
data
  
- Monitoring the status of streaming on both source and destination nodes can be found under
the `org.apache.cassandra.streaming.StreamingService` MBean.  The `Status` attribute gives
an easy indication of what a node is doing with respect to streaming.
+ Monitoring the status of streaming on both source and destination nodes can be found (in
0.6) under the `org.apache.cassandra.streaming.StreamingService` MBean.  The `Status` attribute
gives an easy indication of what a node is doing with respect to streaming.
  
  Step 2 is what takes the most time on most systems. The destination will be idle during
this stage; to monitor anticompaction progress,  you should check the `Compaction` mbean on
the source.
