20130179409 | SEPARATION OF DATA CHUNKS INTO MULTIPLE STREAMS FOR COMPRESSION - For on-line separation of data chunks for compression, unrelated data chunks are classified based on various attributes. The classified data chunks are sent to at least one available compression contexts. The classified data chunks are related. The classified data chunks are encoded by at least one the compression operations. A compression ratio is achieved and included as feedback. | 07-11-2013 |

20130179597 | COMPRESSION BLOCK INPUT/OUTPUT REDUCTION - Exemplary system and computer program product embodiments compression blocks input/output (I/O) reduction are provided. In one embodiment, by way of example only, data blocks are arranged into groups to provide a single I/O. Lists indicating the available block space for the data blocks are organized in advance according to space size. The data blocks required for a single command are allocated as the single I/O. The data blocks are sequentially ordered. Additional system and computer program product embodiments are disclosed and provide related advantages. | 07-11-2013 |

20130262407 | MULTIPLEX CLASSIFICATION FOR TABULAR DATA COMPRESSION - For multiplexer classification for column compression of tabular data, similar type data segments are classified into classes for grouping the data segments into compression streams associated with each one of the classes. The compression streams are encoded based on a class-specific optimized encoding operation. The compression streams into one output buffer, wherein the compression streams are extracted. | 10-03-2013 |

20130275397 | TABLE BOUNDARY DETECTION IN DATA BLOCKS FOR COMPRESSION - Data is converted into a minimized data representation using a suffix tree by sorting data streams according to symbolic representations for building table boundary formation patterns. The converted data is fully reversible for reconstruction while retaining minimal header information. | 10-17-2013 |

20130325821 | MERGING ENTRIES IN A DEDUPLCIATION INDEX - Provided are a computer program product, system, and method for merging entries in a deduplication index. An index has chunk signatures calculated from chunks of data in the data objects in the storage, wherein each index entry includes at least one of the chunk signatures and a reference to the chunk of data from which the signature was calculated. Entries in the index are selected to merge and a merge operation is performed on the chunk signatures in the selected entries to generate a merged signature. An entry is added to the index including the merged signature and a reference to the chunks in the storage referenced in the merged selected entries. The index of the signatures is used in deduplication operations when adding data objects to the storage. | 12-05-2013 |
