### 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 PendingSplits uses HashMap storage. If multiple readers exist and computeIfAbsent is executed at the same time, multiple threads may initialize the map table together. The initial thread's table is overwritten and the split is lost. ### SeaTunnel Version 2.3.3 ### SeaTunnel Config ```conf env { job.mode=BATCH job.name=DEMO } source { Jdbc { url="jdbc:mysql://xxxx/transfer_source" driver="com.mysql.cj.jdbc.Driver" user="root" password="xxxx" query="select * from order_info" partition_column=id partition_num=20 parallelism=2 } } transform { } sink { Jdbc { url="jdbc:mysql://xxxx/transfer_sink?rewriteBatchedStatements=true" driver="com.mysql.cj.jdbc.Driver" user="root" password="xxxx" database="transfer_sink" table="order_info_sink" batch_size=1000 enable_upsert=true generate_sink_sql=true primary_keys = [id] query = "" } } ``` ### Running Command ```shell ./bin/seatunnel-local.sh -c config/savepoint.config ./bin/seatunnel-local.sh -s {jobid} ./bin/seatunnel-local.sh -c config/savepoint.config -r {jobid} ``` ### Error Exception ```log no exception ``` ### Zeta or Flink or Spark Version _No response_ ### Java or Scala Version _No response_ ### 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.
