Learn how Azure Cosmos DB Change Feed can synchronize data into multiple containers, each partitioned for a different query pattern, to avoid expensive cross‑partition scans.
Learn how PostgreSQL materialized views can turn expensive repeated aggregations into fast index‑only reads, with steps to create, query, refresh, and verify the improvement.
Learn how ClickHouse Materialized Views provide incremental, query‑transparent pre‑aggregation that cuts dashboard latency from seconds to sub‑second on high‑cardinality event streams.
Learn how to use the Azure Cosmos DB Change Feed and Change Feed Processor to build event-driven materialized views and implement CQRS patterns for high-performance reads.
