How to write Spark Structured Streaming Data into Hive?

There is df.write().saveAsTable(tablename) however I am not sure if this writes streaming data

I normally do df.writeStream().trigger(new ProcessingTime(1000)).foreach(new KafkaSink()).start() to write streaming data into Kafka but I don't see anything similar to write streaming data into Hive data warehouse. any ideas?

回答1:

df.createOrReplaceTempView("mytable") 
spark.sql("create table mytable as select * from mytable");

or

df.write().mode(SaveMode.Overwrite).saveAsTable("dbName.tableName");
