[jira] [Updated] (SPARK-3865) Dimension table broadcast shouldn't be eager

     [ https://issues.apache.org/jira/browse/SPARK-3865?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Yin Huai updated SPARK-3865:
----------------------------
    Target Version/s: 1.5.0  (was: 1.4.0)

> Dimension table broadcast shouldn't be eager
> --------------------------------------------
>
>                 Key: SPARK-3865
>                 URL: https://issues.apache.org/jira/browse/SPARK-3865
>             Project: Spark
>          Issue Type: Sub-task

> We eagerly broadcast dimension tables in BroadcastJoin. This is bad because even explain would trigger a job to execute the broadcast.
