public String configuration()
Crawler configuration information. This versioned JSON string allows users to specify aspects of a Crawler's behavior.
You can use this field to force partitions to inherit metadata such as classification, input format, output format, serde information, and schema from their parent table, rather than detect this information separately for each partition. Use the following JSON string to specify that behavior:
