> [SPARK-29295|https://issues.apache.org/jira/browse/SPARK-29295] introduces a mechanism that writes to external tables is a dynamic partition method, and the data in the target partition will be deleted first.
> Assuming that 1001 partitions are written, the data of 10001 partitions will be deleted first, but because hive.exec.max.dynamic.partitions is 1000 by default, loadDynamicPartitions will fail at this time, but the data of 1001 partitions has been deleted.
