摘要： A system, method, and computer-readable medium for dynamic detection and management of data skew in parallel join operations are provided. Rows allocated to processing modules involved in a join operation are redistributed among the processing modules by a hash redistribution of the join attributes. Receipt by a processing module of an excessive number of redistributed rows having a skewed value on the join attribute is detected by a processing module which notifies other processing modules of the skewed value. Processing modules then terminate redistribution of rows having a join attribute value matching the skewed value and either store such rows locally or duplicate the rows. The processing module that has received an excessive number of redistributed rows removes rows having a skewed value of the join attribute from a redistribution spool allocated thereto and duplicates the rows to each of the processing modules. The join operation is completed by performing a local join at each processing module and merging the results of the local join operations.

摘要： An energy content meter can spectroscopically quantify oxidation products after oxidation of a combustible mixture. The measured oxidation product concentrations or mole fractions can be converted to an energy content of the un-oxidized combustible mixture using a conversion factor that relates oxygen consumption during oxidation of the combustible mixture to the energy content of the combustible mixture.

摘要： Thermodynamic properties of a natural gas stream can be determined in real time utilizing modeling algorithms in conjunction with one or more sensors for quantifying physical and chemical properties of the natural gas. A first data signal produced by a first sensor can include intensity as a function of wavelength. At least one region in the wavelength range outside of a selected absorption transition can be fitted to a function to obtain a zero-absorption baseline, and a carbon dioxide concentration can be determined based on a line strength at the selected absorption transition corrected by the zero-absorption baseline. A total hydrocarbon concentration in the gas stream can be inferred based on a database of characteristic natural gas concentrations, and an algorithm can be implemented that determines an energy content of the gas stream. Related techniques, apparatus, systems, and articles are also described.

摘要： A system, method, and computer-readable medium for optimizing execution of a join operation in a parallel processing system are provided. A plurality of processing nodes that have at least one row of one or more tables involved in a join operation are identified. For each of the processing nodes, respective counts of rows that would be redistributed to each of the processing nodes based on join attributes of the rows are determined. A redistribution matrix is calculated from the counts of rows of each of the processing nodes. An optimized redistribution matrix is generated from the redistribution matrix, wherein the optimized redistribution matrix provides a minimization of rows to be redistributed among the nodes to execute the join operation.
