> When streaming session finishes, streamed sstabls are added to CFS one by one
> using
> ColumnFamilyStore#addSSTable(https://github.com/apache/cassandra/blob/cassandra-1.0.9/src/java/org/apache/cassandra/streaming/StreamInSession.java#L141).
> This method submits compaction in
> background(https://github.com/apache/cassandra/blob/cassandra-1.0.9/src/java/org/apache/cassandra/db/ColumnFamilyStore.java#L946),
> and end up with unnecessary compaction tasks behind.
