// The policy that specifies update and delete behaviors for the crawler.
//
// The policy tells the crawler what to do in the event that it detects a change in a table that already exists in the customer's database at the time of the crawl. The `SchemaChangePolicy` does not affect whether or how new tables and partitions are added. New tables and partitions are always created regardless of the `SchemaChangePolicy` on a crawler.
//
// The SchemaChangePolicy consists of two components, `UpdateBehavior` and `DeleteBehavior` .
//
// Example:
//   // The code below shows an example of how to instantiate this type.
//   // The values are placeholders you should change.
