Michael Semb Wever commented on CASSANDRA-13701:
------------------------------------------------
Heaps of failures in that^ dtest run.
The failures look legit.
For example
https://ci-cassandra.apache.org/view/patches/job/Cassandra-devbranch-dtest/213/testReport/junit/dtest.materialized_views_test/TestMaterializedViews/test_insert_during_range_movement_rf1/
Thanks to [~dimitarndimitrov] for pointing this out.

> For reasons highlighted in CASSANDRA-7032, the high number of vnodes is not
> necessary. It is very expensive for operations processes and scanning. Its
> come up a lot and its pretty standard and known now to always reduce the
> num_tokens within the community. We should just lower the defaults.
