Re: [DISCUSS] CEP-48: First-Class Materialized View Support

Thanks for the questions. A few clarifications: - *Performance impact & opt-in model:* The new MV synchronization mechanism is fully opt-in. We understand that LWT-backed writes may introduce performance overhead, so users who prefer higher throughput over strict consistency can co

Re: [DISCUSS] CEP-48: First-Class Materialized View Support

If the entire write operation involves additional LWTs to change the MV, it is uncertain whether users can accept the performance loss of such write operations. If this CEP is finally accepted, I think users should at least be given the choice of whether to use the old method or the new method, be

[DISCUSS] CEP-48: First-Class Materialized View Support

Hi everyone, We’d like to propose a new Cassandra Enhancement Proposal: CEP-48: First-Class Materialized View Support . This CEP focuses on addressing the long-standing consistency issues in th
