----------------------------------
Summary: SPIP: Support Spark Materialized View
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
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.
