Subject [jira] [Updated] (SPARK-34322) When refreshing a non-temporary view, also refresh its underlying tables
Date Tue, 02 Feb 2021 06:44:00 GMT

     [ https://issues.apache.org/jira/browse/SPARK-34322?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

feiwang updated SPARK-34322:
----------------------------
    Description: 
For a view, there might be several underlying tables.

In long-running spark server use case, such as zeppelin, kyuubi, livy.

If a table updated, we need refresh this table in current long running spark session.

But if the table is a view, we need refresh the underlying tables one by one.
