   **_Tips before filing an issue_**
   
   - Have you gone through our [FAQs](https://cwiki.apache.org/confluence/display/HUDI/FAQ)?
   
   - Join the mailing list to engage in conversations and get faster support at dev-subscribe@hudi.apache.org.
   
   - If you have triaged this as a bug, then file an [issue](https://issues.apache.org/jira/projects/HUDI/issues) directly.
   
   **Describe the problem you faced**
   
   We are using foreachBatch on spark structured stream to appending data to hudi.
   but seems compaction never happens
   
   **To Reproduce**
   
   Steps to reproduce the behavior:
   
   1.
   ```
   val query: StreamingQuery = inputDF
         .writeStream
         .foreachBatch { (kafkaMessages: DataFrame, batchId: Long) =>
           kafkaMessages
             .write
             .format("hudi")
             .options(hudiOptions)
             .mode(SaveMode.Append)
             .save(s"s3a://daas-hudi-test/york_test/$tableName")
         }
         .trigger(trigger)
         .option("checkpointLocation", s"${params.baseOutputFolder}/spark-checkpoint")
         .start()
   ```
   
   ```

   @zherenyu831 : Can you model your query using pure structured streaming APIs and avoid foreachBatch. It looks like foreachBatch is triggering batch sink and not streaming sink APIs. We will have a blog shortly on the usage but you can reference the PR : https://github.com/apache/hudi/pull/1996/files#diff-cb5b78d0c2deafe117b643f5de250a17R50
   
   Also, please note that we have discovered an issue related to batch writes https://issues.apache.org/jira/browse/HUDI-1230
   I have sent an email to dev@ and users@ Mailing list on the config change to workaround.

   @bvaradar 
   Thank you for reply, I also saw your blog pr before, and it work with pure structured streaming api
   Marked, will try to avoid this issue when batch writing
