I need to listen to multiple kafka topics and save messages to corresponding tables. Does DeltaStreamer allow that? and does the processing of each stream/topic run in parallel? 2. I am also exploring Spark Streaming and using Spark DataSource. basically something like this `DSTREAM.map(x =>(x.topic, List(x.value()))) .reduceByKey(_:::_) .map(processAndSavetoHudi) .print() ` Is it possible to run hudi upserts from the executor tasks (i.e. from the Dstream.map function) ? The foreachrdd function doesn't process streams in parallel, so I am trying to use the map function and save each stream to hudi from the workers. A clear and concise description of the problem. **To Reproduce** Steps to reproduce the behavior: 1. 2. 3. 4. **Expected behavior** A clear and concise description of what you expected to happen. **Environment Description** * Hudi version : 5.2 * Spark version : 2.4.5. * Hive version : 2.3.3 * Hadoop version : 2.8 * Storage (HDFS/S3/GCS..) : no * Running on Docker? (yes/no) : **Additional context** Add any other context about the problem here. **Stacktrace** ```Add the stacktrace of the error.``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
