    摘要: Exemplary method, system, and computer program product embodiments for efficient garbage collection in a compressed journal file system are provided. In one embodiment, by way of example only, a map corresponding to data blocks with overwritten compressed journal entries is configured. Weighted conditions for each of the overwritten compressed journal entries are calculated. The weighted conditions are arranged in the map from lowest to highest. One of the weighted conditions includes a biasing variable towards selecting data blocks having free space at an end of at least one associated record. Additional system and computer program product embodiments are disclosed and provide related advantages.

    摘要: Exemplary method, system, and computer program product embodiments for real-time column compression of data are provided. In one embodiment, by way of example only, a data structure is estimated for an initially unknown structured data. The estimated data structure is placed in a stream. A columnar compression operation is applied to the stream to generate an achieved compression ratio. The stream is compressed. Feedback of the achieved compression ratio is analyzed from the stream to determine if an optimal one of the columnar compression operations has been applied. If the optimal one of the columnar compression operations has been applied, the actual data structure of the initially unknown structured data is determined.

    摘要: Various embodiments for operating a transformation system, capable of transforming a logical data object (LO) to a transformed logical data object (TLO), are provided. In one such embodiment, an open LO request to a certain LO and addressed by the at least one client to the at least one storage device, is intercepted. An identifier (ID) in a header of a TLO corresponding to the requested LO and stored in the at least one storage device, is obtained. The obtained ID is used to characterize the TLO and the LO. A determination is made whether the transformation system handles at least one open LO characterized by an ID with a same value as the obtained ID. The requested LO is opened if at least one open LO is not found. An instance corresponding to the intercepted open LO request is generated. The instance is associated to the obtained ID.
