1. A method for managing a logical data object stored in a storage device, the method comprising: storing, in a transformed logical data object in the storage device, index data in an index block; storing, in the transformed logical data object, indexed data in the index data as persistent data in a first portion of a data block; storing, in the transformed logical data object, non-indexed data in the index data as semi-persistent data in a second portion of the data block; periodically flushing the semi-persistent data to persistent data in the first portion; and updating the index data with the persistent data each time the semi-persistent data is periodically flushed upon an index flush event, wherein: the semi-persistent data remains non-indexed until a periodic flush, and the storage device comprises persistent data subsequent to each periodic flush.
