> Key: SPARK-29038
> URL: https://issues.apache.org/jira/browse/SPARK-29038
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Lantao Jin
> Priority: Major
>
> Materialized view is an important approach in DBMS to cache data to
> accelerate queries. By creating a materialized view through SQL, the data
> that can be cached is very flexible, and needs to be configured arbitrarily
> according to specific usage scenarios. The Materialization Manager
> automatically updates the cache data according to changes in detail source
> tables, simplifying user work. When user submit query, Spark optimizer
> rewrites the execution plan based on the available materialized view to
> determine the optimal execution plan.
