### Search before asking - [X] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened The amount of data is 15 million rows. The speed of extracting hive data to mysql can only reach 13,000 records per second, and it takes nearly 30 minutes to complete the extraction. But I set the seatunnel parallelism parameter to 10. After the data extraction task started, I used the show processlist command on the MySQL client and found that there was only one insert thread. Then I tested extracting hive data to the console. The same amount of data took less than 1 minute. ### SeaTunnel Version 2.3.1 and 2.3.5 ### SeaTunnel Config ```conf env { execution.parallelism = 10 job.mode = "BATCH" } source { Hive { table_name = "" metastore_uri = "${metastore_uri}" result_table_name = "Table_test" hdfs_site_path = "" hive_site_path = "" } } transform { sql { source_table_name="Table_test" query = "select xxx from Table_test" result_table_name = "Table_test2" } } sink { Jdbc { url = "${url}" driver = "${driver}" user = "${user}" password = "${password}" database = "${mysql_db}" batch_size = 20000 table = "" query = "insert into table_name (xxx) values(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)" } } ``` ### Running Command ```shell I use the seatunnel module on dolphinscheduler to run in cluster mode. I also submitted from the command line using: ./bin/seatunnel.sh --config ./config/test.config ``` ### Error Exception ```log No exception occurred, just did not meet expectations ``` ### Zeta or Flink or Spark Version Zeta ### Java or Scala Version 1.8 ### Screenshots _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
