Hi For us, clearly the willing to improve (and not give up) materialized views with a quality testing follow up https://issues.apache.org/jira/browse/CASSANDRA-15921
Materialized view is a fantastic tool very useful for us. Our use case is to deduplicate and order : We want to store the last visit between 2 members and for one member given get all visits ordered from the most recent to the older. Basically : Table PK : (member_id_sender, member_id_receiver) MV PK : (member_id_sender, visit_date, member_id_receiver) - > The table deduplicates... The MV orders... Coding such a feature is very complicated and not necessarily most reliable than what MV can do Indeed, sometimes materialized views can have some errors (but few...not so critical of us, we have a tool to check and fix them). Our main pain is MV management during a new node bootstrapping. Very impatient to see if C4 improve that.

What feature or fix of the 4.0 release is most important for your use case(s)/environment? What is working well so far? What needs more work? Is there anything that needs more explanation?
