[jira] [Comment Edited] (BEAM-7835) Support Triggered
PCollectionView Join Unbounded windowed PCollection in BeamSQL
[ https://issues.apache.org/jira/browse/BEAM-7835?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16922776#comment-16922776 ]

--------------------------------------------------------
In the short term, adding this rule sounds good to me as it mutually exclusive with current unbounded-unboudned CoGBK implementation which does not allow non default trigger.
Once we loose the constraint of unbounded-unbounded CoGBK join to allow non default trigger, there will be overlapping between the new rule with current existing rule, it would be an open question how to distinguish these two cases (maybe through isView property). Because of this, I would suggest you tag the new rule with experimental flag and explicitly says it's an experimental feature without guaranteeing backward compatibility. So in case there will be conflict and we will need some changes.
