摘要： Methods, systems, and apparatus for identifying two or more files, each of which include multiple entries, determining a respective size of each of the files, each size being an estimate of how many distinct entries exist in the respective file that are not garbage entries, determining a combined size of the files, where the combined size of the files is an arithmetic sum of the respective sizes of the files, estimating a compacted size of the files, where the estimated compacted size of the files is an estimate of how many distinct entries exist in the files that are not garbage entries, selecting the two or more files for compaction, based at least on a comparison of the combined size of the files to the estimated compacted size of the files, and compacting the two or more selected files.

摘要： A computer-implemented method for selecting file-recall modes based on environmental properties may include: 1) identifying a request to recall a file from a secondary storage system to a primary storage system, 2) identifying at least one environmental property associated with the file, 3) selecting, based at least in part on the identified environmental property, a recall mode for recalling the file, and then 4) recalling the file from the secondary storage system to the primary storage system using the selected recall mode. Various additional methods, systems, and configured computer-readable-storage media are also disclosed.
