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

             Summary: Improve the way we do streaming with vnodes
                 Key: CASSANDRA-10495
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10495
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Marcus Eriksson
             Fix For: 3.x


Streaming with vnodes usually creates a large amount of sstables on the target node - for
example if each source node has 100 sstables and we use num_tokens = 256, the bootstrapping
(for example) node might get 100*256 sstables

One approach could be to do an on-the-fly compaction on the source node, meaning we would
only stream out one sstable per range. Note that we will want the compaction strategy to decide
how to combine the sstables, for example LCS will not want to mix sstables from different
levels while STCS can probably just combine everything
