Jordan West updated CASSANDRA-14529:
------------------------------------
Status: Patch Available (was: Open)
Made the cache invalidation run after the files are added to the tracker. This
is similar to
[streaming|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/streaming/CassandraStreamReceiver.java#L207-L210].
There is still a race condition but the worst case is only invalidation of a
cached copy of the newly added data.
Branch: [https://github.com/jrwest/cassandra/commits/14529-trunk]

> CASSANDRA-6719 introduced {{nodetool import}} with row cache invalidation,
> which [occurs before adding new sstables to the
> tracker|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/SSTableImporter.java#L137-L178].
> Stale reads will result after a read is interleaved with the read row's
> invalidation and adding the containing file to the tracker.
