    By default (single-schema mode) the metadata table is placed in the default schema for the connection provided by the datasource.
    
    When the flyway.schemas property is set (multi-schema mode), the metadata table is placed in the first schema of the list.
    
    Returns:

  - getSchemas
```
String[] getSchemas()
```
    Retrieves the schemas managed by Flyway. These schema names are case-sensitive.
    Consequences:
    - The first schema in the list will be automatically set as the default one during the migration.
    - The first schema in the list will also be the one containing the metadata table.
    - The schemas will be cleaned in the order of this list.
    Returns:
    
    The schemas managed by Flyway. (default: The default schema for the datasource connection)

String[] getLocations()
```
    Retrieves the locations to scan recursively for migrations.
    
    The location type is determined by its prefix. Unprefixed locations or locations starting with classpath: point to a package on the classpath and may contain both sql and java-based migrations. Locations starting with filesystem: point to a directory on the filesystem and may only contain sql migrations.
    
    Returns:
    
    Locations to scan recursively for migrations. (default: db/migration)
  - isBaselineOnMigrate
```
boolean isBaselineOnMigrate()
```
    Whether to automatically call baseline when migrate is executed against a non-empty schema with no metadata table. This schema will then be initialized with the baselineVersion before executing the migrations. Only migrations above baselineVersion will then be applied.
    
    This is useful for initial Flyway production deployments on projects with an existing DB.
    
    Be careful when enabling this as it removes the safety net that ensures Flyway does not migrate the wrong database in case of a configuration mistake!
    
    Returns:
    
    true if baseline should be called on migrate for non-empty schemas, false if not. (default: false)
  - isOutOfOrder
```
boolean isOutOfOrder()
```
    Allows migrations to be run "out of order".
    If you already have versions 1 and 3 applied, and now a version 2 is found, it will be applied too instead of being ignored.
    
    Returns:
    
    true if outOfOrder migrations should be applied, false if not. (default: false)
  - isIgnoreMissingMigrations
```
boolean isIgnoreMissingMigrations()
```
    Ignore missing migrations when reading the metadata table. These are migrations that were performed by an older deployment of the application that are no longer available in this version. For example: we have migrations available on the classpath with versions 1.0 and 3.0. The metadata table indicates that a migration with version 2.0 (unknown to us) has also been applied. Instead of bombing out (fail fast) with an exception, a warning is logged and Flyway continues normally. This is useful for situations where one must be able to deploy a newer version of the application even though it doesn't contain migrations included with an older one anymore.
    
    Returns:
    
    true to continue normally and log a warning, false to fail fast with an exception. (default: false)
  - isIgnoreFutureMigrations
```
boolean isIgnoreFutureMigrations()
```
    Ignore future migrations when reading the metadata table. These are migrations that were performed by a newer deployment of the application that are not yet available in this version. For example: we have migrations available on the classpath up to version 3.0. The metadata table indicates that a migration to version 4.0 (unknown to us) has already been applied. Instead of bombing out (fail fast) with an exception, a warning is logged and Flyway continues normally. This is useful for situations where one must be able to redeploy an older version of the application after the database has been migrated by a newer one.
    
    Returns:
    
    true to continue normally and log a warning, false to fail fast with an exception. (default: true)
  - isValidateOnMigrate
```
boolean isValidateOnMigrate()
```
    Whether to automatically call validate or not when running migrate.
    
    Returns:
    
    true if validate should be called. false if not. (default: true)
  - isCleanOnValidationError
```
boolean isCleanOnValidationError()
```
    Whether to automatically call clean or not when a validation error occurs.
    This is exclusively intended as a convenience for development. Even tough we strongly recommend not to change migration scripts once they have been checked into SCM and run, this provides a way of dealing with this case in a smooth manner. The database will be wiped clean automatically, ensuring that the next migration will bring you back to the state checked into SCM.
    
    Warning ! Do not enable in production !
    
    Returns:
    
    true if clean should be called. false if not. (default: false)
  - isCleanDisabled
```
boolean isCleanDisabled()
```
    Whether to disable clean.
    This is especially useful for production environments where running clean can be quite a career limiting move.
    
    Returns:
    
    true to disabled clean. false to leave it enabled. (default: false)
  - isAllowMixedMigrations
```
@Deprecated
boolean isAllowMixedMigrations()
```
    Deprecated. Use isMixed() instead. Will be removed in Flyway 5.0.
    
    Whether to allow mixing transactional and non-transactional statements within the same migration.
    
    Returns:
    
    true if mixed migrations should be allowed. false if an error should be thrown instead. (default: false)
  - isMixed
```
boolean isMixed()
```
    Whether to allow mixing transactional and non-transactional statements within the same migration.
    
    Returns:
    
    true if mixed migrations should be allowed. false if an error should be thrown instead. (default: false)
  - isGroup
```
boolean isGroup()
```
    Whether to group all pending migrations together in the same transaction when applying them (only recommended for databases with support for DDL transactions).
    
    Returns:
    
    true if migrations should be grouped. false if they should be applied individually instead. (default: false)
  - getInstalledBy
```
String getInstalledBy()
```
    The username that will be recorded in the metadata table as having applied the migration.
    
    Returns:
    
    The username or null for the current database user of the connection. (default: null).
