[jira] [Updated] (SPARK-18801) Support resolve a nested view
[ https://issues.apache.org/jira/browse/SPARK-18801?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Dongjoon Hyun updated SPARK-18801: -- Fix Version/s: 2.2.0 > Support resolve a nested view > - > > Key: SPARK-18801 > URL: https://issues.apache.org/jira/browse/SPARK-18801 > Project: Spark > Issue Type: Sub-task > Components: SQL >Reporter: Jiang Xingbo >Assignee: Jiang Xingbo > Fix For: 2.2.0 > > > We should be able to resolve a nested view. The main advantage is that if you > update an underlying view, the current view also gets updated. > The new approach should be compatible with older versions of SPARK/HIVE, that > means: > 1. The new approach should be able to resolve the views that created by > older versions of SPARK/HIVE; > 2. The new approach should be able to resolve the views that are > currently supported by SPARK SQL. > The new approach mainly brings in the following changes: > 1. Add a new operator called `View` to keep track of the CatalogTable > that describes the view, and the output attributes as well as the child of > the view; > 2. Update the `ResolveRelations` rule to resolve the relations and > views, note that a nested view should be resolved correctly; > 3. Add `AnalysisContext` to enable us to still support a view created > with CTE/Windows query. -- This message was sent by Atlassian JIRA (v6.4.14#64029) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
