Paulo Motta commented on CASSANDRA-10341:
-----------------------------------------
I thought of iterating over all the received {{SSTableReader}} keys on
{{StreamReceiveTask.OnCompletionRunnable}} and invalidate the keys before
adding them to {{ColumnFamilyStore}}. Is this a valid approach or do you think
there is a more efficient way of doing this, [~benedict]? Do we want to perform
the cache invalidation and addition of sstables to {{ColumnFamilyStore}}
atomically, or is it acceptable to invalidate just before adding?
> Streaming does not guarantee cache invalidation

> Looking at the code, we attempt to invalidate the row cache for any rows we
> receive via streaming, however we invalidate them immediately, before the new
> data is available. So, if it is requested (which is likely if it is "hot") in
> the interval, it will be re-cached and not invalidated.
