Materialized views in Aiven for ClickHouse optimize queries for speed and freshness, making it ideal for analytics wherever your data lives. Businesses can use materialized views to effectively harness their abundance of data and discover insights into products or customers. By storing the output of a query, materialized views allow for faster retrieval of data compared to traditional views that don't store data themselves. ClickHouse's implementation of materialized views leverages columnar storage for higher compression and faster query performance, as well as efficient refreshes of the materialized views. Aiven for Apache Kafka can be integrated with ClickHouse to ensure real-time data analytics by triggering an MV with each event to persist that data and update any associated queries.
