#### [  Java  ]

```

        UpdateTableRequest updateTableRequest = new UpdateTableRequest();
        updateTableRequest.setDatabaseName(DATABASE_NAME);
        updateTableRequest.setTableName(TABLE_NAME);

        // Can update enforcement level for dimension type partition key with OPTIONAL or REQUIRED enforcement
        final List<PartitionKey> partitionKeyWithDimensionAndRequiredEnforcement = Collections.singletonList(new PartitionKey()
