Subject [SAMZA-690] Changelog topic creation should not be in the container code
Date Thu, 25 Jun 2015 14:40:07 GMT
Hello all,

Description of SAMZA-690 ( ticket says that
creation of changelog and checkpoint topics should be moved from SamzaContainer class to JobRunner/JobCoordinator
class. I investigated for a while, but seem to have hit a wall and require some help. I have
a few questions regarding this task:

1.       Is checkpoint topic referred to in the description coordinator stream/topic?

2.       Changelog topic creation is handled by TaskStorageManager class which is required
by SamzaContainer. Would it be preferable to:

a.       Create TaskStoreManager instance(s) in JobRunner and pass them to SamzaContainer

b.      Create changelog stream in JobRunner/JobCoordinator and skip it in TaskStoreManager

Met vriendelijke groet / Kind regards,
