    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.

    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： In a storage system, using a pool of encryption processing cores, the encryption processing cores are assigned to process either encryption operations, decryption operations, and decryption and encryption operations, that are scheduled for processing. A maximum number of the encryption processing cores are set for processing only the decryption operations, thereby lowering a decryption latency. A minimal number of the encryption processing cores are allocated for processing the encryption operations, thereby increasing encryption latency. Upon reaching a throughput limit for the encryption operations that causes the minimal number of the plurality of encryption processing cores to reach a busy status, the minimal number of the plurality of encryption processing cores for processing the encryption operations is increased.

    摘要： There are provided a method of transforming a non-transformed stored logical data object (LO) device into a transformed LO and system thereof. The method comprises: a) in response to a respective transformation request, logically dividing the non-transformed LO in a first segment and one or more non-transformed subsequent segments, the segments having predefined size; b) generating a header for the respective transformed LO; c) processing said first segment; d) overwriting said first segment by said generated header and said transformed first segment; e) indexing said first transformed segment and said one or more non-transformed subsequent segments as constituting a part of said transformed LO; f) generating at least one index section; and g) updating the indication in the header to point that the non-transformed LO has been transformed in the transformed LO comprising said generated header, said first transformed segment, said one or more subsequent segments comprising data in non-transformed form and said at least one index section.
