When designing a data model in Cassandra, which of the following is the most critical factor to consider?

Ensuring all tables are in third normal form

Minimizing the number of tables

Denormalization and query patterns

Normalization of data

None

In Cassandra, data modeling should focus on denormalization and query patterns to ensure efficient read and write operations, as opposed to traditional normalization.

Which CQL optimization technique can help reduce the read latency for frequently accessed data?

Using materialized views

Implementing secondary indexes

Using a smaller replication factor

Caching data at the application layer

None

Materialized views can help optimize read performance by precomputing and storing query results, reducing the need for complex queries.
