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： There is provided a compression system configured to compress logical data objects into one or more accommodation blocks with a predefined size, and a method of operating thereof. The compression system comprises a compression engine capable of compressing input data with the help of sequential encoding one or more input strings and a counter operatively coupled to the compression engine. The counter is configured to keep its ongoing value indicative of a number of input bytes in one or more strings successfully encoded into a given accommodation block; and, responsive to unsuccessful compression of a string into the given accommodation block, to provide the compression engine with information indicative of starting point in the input stream for encoding into the next accommodation block, thus giving rise to a “start indication”.

摘要： Various embodiments for transforming a logical data object for storage in a storage device operable with at least one storage protocol are provided. In one such embodiment, the logical data object into one or more segments are divided with each segment characterized by respective start and end offsets. One or more obtained variable size data chunks are processed corresponding to the logical data object to obtain processed data chunks, wherein at least one of the processed data chunks comprises transformed data resulting from the processing. Each of the variable size data chunks is associated with a respective segment of the logical data object. The processed data chunks are sequentially accommodated in accordance with an order of chunks received while keeping the association with the respective segments.

摘要： Systems capable of transformation of logical data objects for storage and methods of operating thereof are provided. One method includes identifying among a plurality of requests addressed to the storage device two or more “write” requests addressed to the same logical data object, deriving data chunks corresponding to identified “write” requests and transforming the derived data chunks, grouping the transformed data chunks in accordance with the order the requests have been received and in accordance with a predefined criteria, generating a grouped “write” request to the storage device, and providing mapping in a manner facilitating one-to-one relationship between the data in the obtained data chunks and the data to be read from the transformed logical object. The method further includes obtaining an acknowledging response from the storage device, multiplying the obtained acknowledging response, and sending respective acknowledgements to each source that initiated each respective “write” request.
