Examples of SecondaryConfig

com.sleepycat.db.SecondaryConfig
The configuration properties of a SecondaryDatabase extend those of a primary Database. The secondary database configuration is specified when calling {@link Environment#openSecondaryDatabase Environment.openSecondaryDatabase}.
To create a configuration object with default attributes:
```
 SecondaryConfig config = new SecondaryConfig(); 
```
To set custom attributes:
```
 SecondaryConfig config = new SecondaryConfig(); config.setAllowCreate(true); config.setSortedDuplicates(true); config.setKeyCreator(new MyKeyCreator()); 
```
NOTE: There are two situations where the use of secondary databases without transactions requires special consideration. When using a transactional database or when doing read operations only, this note does not apply.
- If secondary is configured to not allow duplicates, when the secondary is being updated it is possible that an error will occur when the secondary key value in a record being added is already present in the database. A DatabaseException will be thrown in this situation.
- If a foreign key constraint is configured with the delete action ABORT (the default setting), a DatabaseException will be thrown if an attempt is made to delete a referenced foreign key.
In both cases, the operation will be partially complete because the primary database record will have already been updated or deleted. In the presence of transactions, the exception will cause the transaction to abort. Without transactions, it is the responsibility of the caller to handle the results of the incomplete update or to take steps to prevent this situation from happening in the first place.
