Hey. I have a problem creating a materialized view.
My case is quite similar to
https://issues.apache.org/jira/browse/CASSANDRA-13564
but discussion in comments there faded, let me describe by case.

we are trying Cassandra as an alternative for storage huge stream of data
coming from our customers.
Storing works quite fine, and I started to validate how retrieval does. We
have two types of that: fetching specific records and bulk retrieval for
