Basically we register ``` stateMgr.registerStore(persistentStore, persistentStore.stateRestoreCallback); stateMgr.registerStore(persistentStoreTwo, persistentStoreTwo.stateRestoreCallback); stateMgr.registerStore(nonPersistentStore, nonPersistentStore.stateRestoreCallback); ``` but only write the checkpoint for the `persistentStorePartition`, nonPersistentStorePartition` and `irrelevantPartition`. I think the point of the `irrelevantPartition` is to make sure that we detect that the `persistentStoreTwoPartition` offset is missing even though the checkpoint technically has the correct number of offsets in total. ie, that we actually map the offsets to a registered changelog ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
