[jira] [Assigned] (SPARK-28199) Move Trigger implementations to
Triggers.scala and avoid exposing these to the end users
[ https://issues.apache.org/jira/browse/SPARK-28199?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sean Owen reassigned SPARK-28199:
---------------------------------
Docs Text: In Spark 3.0, the deprecated class org.apache.spark.sql.streaming.ProcessingTime has been removed. Use org.apache.spark.sql.streaming.Trigger.ProcessingTime() instead. Likewise, org.apache.spark.sql.execution.streaming.continuous.ContinuousTrigger has been removed in favor of Trigger.Continuous(), and org.apache.spark.sql.execution.streaming.OneTimeTrigger has been hidden in favor of Trigger.Once().

> Components: Structured Streaming

> Even ProcessingTime is deprecated in 2.2.0, it's being used in Spark codebase, and actually the alternative Spark proposes use deprecated methods which feels like circular - never be able to remove usage.
> In fact, ProcessingTime is deprecated because we want to only expose Trigger.xxx instead of exposing actual implementations, and I think we miss some other implementations as well.
> This issue targets to move all Trigger implementations to Triggers.scala, and hide from end users.
