             Summary: Add a parameter to limit the number of dynamic partitions for data source table
                 Key: SPARK-29166
                 URL: https://issues.apache.org/jira/browse/SPARK-29166
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.4.4, 3.0.0
            Reporter: Lantao Jin


Dynamic partition in Hive table has some restrictions to limit the max number of partitions. See https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DML#LanguageManualDML-DynamicPartitionInserts

It's very useful to prevent to create mistake partitions like ID. Also it can protect the NameNode from mass RPC calls of creating.
