@Deprecated public interface ManagedDataSource<T>
Deprecated.
since 9.5 - use SpaceDataSource or SpaceSynchronizationEndpoint instead.
ManagedDataSource should be implemented when initialization and shutdown operations are needed by the data source.

Usually in case of external databases - init() will establish a JDBC connection and shutdown() will close it.

If the implementation requires configuration, it can be configured in external properties file.
The content of this file is passed to init() The location of the properties file should be defined in the space schema or property:

space-config.ExternalDataSource.init-properties-file
