> During the compaction test task (CASSANDRA-16345), we discovered that when
> zero copy streaming (ZCS) is enabled, it can lead to the streamed files
> contain tokens that exceed the disk boundaries (only when using multiple data
> directories) on the target host. Since ZCS streams the entire SSTable as is.
> We should add a proper note to the
> [https://cassandra.apache.org/doc/latest/new/streaming.html#zero-copy-streaming]
> section to inform people when using the feature.
