CREATE MATERIALIZED VIEW

Giriş

Açıklaması şöyle

Materialized views are precomputed views of data that are stored on disk and can be accessed more quickly than regular views. By using materialized views, queries can be executed more efficiently, especially for complex aggregations and joins.

Açıklaması şöyle

Materialized views are typically used in situations where a complex query needs to be executed frequently or where the query result takes a long time to compute. By precomputing the result and storing it in a materialized view (virtual tables), queries can be executed more quickly and with less overhead. PostgreSQL, Microsoft SQL Server, RisingWave or Materialize support materialized views with automatic updates.
