  19. def isPartialWriteVisible(path: Path, hadoopConf: Configuration): Boolean

    Whether a partial write is visible when writing to path.

    Whether a partial write is visible when writing to path.

    As this depends on the underlying file system implementations, we require the input of path here in order to identify the underlying file system, even though in most cases a log store only deals with one file system.

    The default value is only provided here for legacy reasons, which will be removed. Any LogStore implementation should override this instead of relying on the default.

    Note: The default implementation ignores the hadoopConf parameter to provide the backward compatibility. Subclasses should override this method and use hadoopConf properly to support passing Hadoop file system configurations through DataFrame options.

An implementation should provide a more efficient approach if possible. For example, the file content can be loaded on demand.

    Note: the returned ClosableIterator should be closed when it's no longer used to avoid resource leak.
