摘要： An apparatus comprises a hardware accelerator coupled to a memory. The hardware accelerator comprises one or more decompression units. The one or more decompression units are reconfigurable. The hardware accelerator may be a field-programmable gate array. The hardware accelerator may also comprise one or more reconfigurable scanner units. The one or more decompression units, in the aggregate, are operative to decompress one or more rows of a database at a bus speed of the coupling between the hardware accelerator and the memory. Two or more decompression units are operative to decompress two or more rows of a database in parallel. The apparatus allows for hardware accelerated row decompression.

摘要： Techniques are provided for hardware-accelerated relational joins. A first table comprising one or more rows is processed through a hardware accelerator. At least one join column in at least one of the one or more rows of the first table is hashed to set at least one bit in at least one bit vector. A second table comprising one or more rows is processed through a hardware accelerator. At least one join column in at least one of the one or more rows of the second table is hashed to generate at least one hash value. At least one bit vector is probed using the at least one hash value. A joined row is constructed responsive to the probing step. The row-construction step is performed in the hardware accelerator.

摘要： Techniques are provided for encoded data processing which allows for continuous data processing as encoded data changes. Data is decomposed into one or more blocks with each block containing at least one data record. At least one data record within a given block is encoded with a first encoding process selected from one or more encoding processes. The first encoding process is associated with the given data block. Techniques evaluate whether or not to implement an encoding change for a given block when updating a given data record in the given block. Responsive to the evaluation, the given block is re-encoded with a second encoding process. Responsive to the re-encoding, the association of the given block is updated. A map is formed to convert the given data record encoded with the first encoding process to the second encoding process so as to preserve comparative relationships of the given data record.
