请改用org.apache.spark.sql.streaming.Trigger.ProcessingTime。 同样,删除org.apache.spark.sql.execution.streaming.continuous.ContinuousTrigger是为了支持Trigger.Continuous,隐藏org.apache.spark.sql.execution.streaming.OneTimeTrigger是为了支持Trigger.Once。 请参阅SPARK-28199。
在Databricks Runtime 11.3 LTS 及更高版本中,Trigger.Once 设置被弃用。 Databricks 建议对所有增量式批处理工作负载使用 Trigger.AvailableNow。“立即可用”触发器选项将所有可用记录用作一个增量批,并且让你能够使用 maxBytesPerTrigger 等选项配置批大小(大小选项因数据源而异)。Azure Databricks 支持使用 Trigger....
同樣地, org.apache.spark.sql.execution.streaming.continuous.ContinuousTrigger 已被移除贊成 Trigger.Continuous,並 org.apache.spark.sql.execution.streaming.OneTimeTrigger 一直隱藏在贊成 Trigger.Once。(SPARK-28199) 在Databricks Runtime 7.0 中,讀取 Hive SerDe 資料表時,根據預設,Spark 不允許在不是數據表...

In our streaming implementation, we need to perform the following steps: We need to connect to Azure Event Hubs. We need to set up an input data stream which reads from Event Hubs. Once we have read a micro-batch of events from the input stream, we need to p...
