Hi Team, I am facing one weird issue, When am running MERGE sql inside Spark Structured Streaming foreachbatch it takes about 300+ seconds to complete. But when I ran it as independent sql in spark-shell it gets completes in just 25 seconds. Almost facing 10X degrade when am running inside my batch. But both cases am registering and using my batch df as physical table. Anyone faced like this issue before?.

Could it be parallelizing the data ?
