> -If I understood the iterator transformations introduced by CASSANDRA-9975 correctly,-
[ReadCommand.CheckForAbort|https://github.com/apache/cassandra/blob/cassandra-3.11/src/java/org/apache/cassandra/db/ReadCommand.java#L541]
should apply itself before returning a partition. At the moment it is applied to row iterators
for single command partitions, but for range queries -I think- it only monitors the query
progress when a new partition is iterated, not when a new row is iterated. So for large partitions,
we may fail to log a query as slow, or fail to abort it if the RPC timeout is exceeded.
