Hi Marc.
No, I didn´t take a look at the Streamflow implementation, thanks for the
pointer. I just had a look at it, and it seems like I have a similar setup in
my application, except for the eager upgrade of entities in
StartupMigrationService (which was a nice touch). But I could not find any
usage of the MigrationOperation interface in that code either. That is the
interface I have a hard time figuring out how to use.:
public interface MigrationOperation
{
void upgrade( StateStore stateStore, Migrator migrator )
throws IOException;
...
}
The StateStore interface only has one method:
JSONObject getState( String id ) throws IOException;
This method expect me to know the id of the object that I am looking for, but
the problem is there does not seem to be any way to find this information. Does
anyone have an example of how to use the MigrationOperation interface?
Thanks.
Best regards
