[jira] [Commented] (BEAM-7195) BigQuery - 404 errors for 'table not found' when using dynamic destinations - sometimes, new table fails to get created

["Reuven Lax (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BEAM-7195?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17213454#comment-17213454 ] 

Reuven Lax commented on BEAM-7195:
----------------------------------

Some more details:

The bug is that BigQueryIO assumed that Reshuffle would produce pane indices like a GroupByKey would. However Reshuffle merely forwards whatever pane indices already existed, and in this case those were produced by the previous GroupByKey onto a singleton. The PR fixes this by making sure that the prior GroupByKey groups by destination instead of by singleton.
