  - checkIfLoaded
```
public void checkIfLoaded()
```
  - startLoading
```
public void startLoading()
```
    Description copied from interface: RecordStore
    
    Starts the map loader if there is a configured and enabled MapLoader and the key loading has not already been started. The loading may start again if there was a migration and the record store on the migration source has started but not completed the loading.
  - setPreMigrationLoadedStatus
```
public void setPreMigrationLoadedStatus(boolean loaded)
```
    Description copied from interface: RecordStore
    
    Informs this recordStore about the loading status of the recordStore that this store is migrated from. If the record store on the migration source has been loaded then this record store should NOT trigger the load again. Will be taken into account only if invoked before RecordStore.startLoading(), otherwise has no effect.
    This method should be deleted when the map's lifecycle has been cleaned-up. Currently it's impossible to pass additional state when the record store is created, thus this state has to be passed in post-creation setters which is cumbersome and error-prone.
  - isLoaded
```
public boolean isLoaded()
```
    Description copied from interface: RecordStore
    
    Returns true if all key and value loading tasks have completed on this record store.
  - loadAll
```
public void loadAll(boolean replaceExistingValues)
```
    Description copied from interface: RecordStore
    
    Triggers key and value loading if there is no ongoing or completed key loading task, otherwise does nothing. The actual loading is done on a separate thread.
    
    Parameters:
    
    replaceExistingValues - if the existing entries for the loaded keys should be replaced
  - loadAllFromStore
```
public void loadAllFromStore(List<Data> keys,
                             boolean replaceExistingValues)
```
    Description copied from interface: RecordStore
    
    Triggers loading values for the given keys from the defined MapLoader. The values will be loaded asynchronously and this method will return as soon as the value loading task has been offloaded to a different thread.
    
    Parameters:
    
    keys - the keys for which values will be loaded
    
    replaceExistingValues - if the existing entries for the keys should be replaced with the loaded values
  - updateLoadStatus
```
public void updateLoadStatus(boolean lastBatch,
                             Throwable exception)
```
    Description copied from interface: RecordStore
    
    Advances the state of the map key loader for this partition and sets the key loading future result if the lastBatch is true.
    If there was an exception during key loading, you may pass it as the exception paramter and it will be set as the result of the future.
    
    Parameters:
    
    lastBatch - if the last key batch was sent
    
    exception - an exception that occurred during key loading
  - maybeDoInitialLoad
```
public void maybeDoInitialLoad()
```
    Description copied from interface: RecordStore
