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. > Details in [design > doc|https://docs.google.com/document/d/1q5pjSWoTNVc9zsAfbNzJ-guHyVwPsEroIEP8Cca179A/edit?usp=sharing] -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
