Publication number: 20150234852Abstract: Identification of data candidates for data processing is performed in real time by a processor device in a computing environment. Data candidates are sampled for performing a classification-based compression upon the data candidates. A heuristic is computed on a randomly selected data sample from the data candidate for determining if the data candidate may benefit from the classification-based compression, wherein a ratio is summed between the actual number of the characters and the expected number of the characters, and then dividing the ratio by a number of the data classes that are not empty, wherein the non-classifiable data are included in the number of the data classes during the dividing, and the number of the data classes, that are not empty, have characters that belong to the class that were observed in the input; and the classification-based compression is performed on the data candidates if the ratio exceeds a threshold.Type: ApplicationFiled: May 5, 2015Publication date: August 20, 2015Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Jonathan AMIT, Lilia DEMIDOV, George GOLDBERG, Nir HALOWANI, Ronen I.
