Abstract
An apparatus includes a processor to: instantiate data buffers of a queue, reading threads, and provision threads; within each reading thread, use an identifier provided in a data buffer of the queue to retrieve the corresponding data set part and part metadata from storage device(s), and store both within the data buffer; operate the queue as a (FIFO) buffer; within each provision thread, retrieve a row group from among multiple row groups and corresponding metadata from within the data buffer, use information in the metadata to decompress at least one column, and provide the data values of the row group to the requesting device or an application routine; and in response to each instance of storage of a data set part within a data buffer of the queue, analyze the availability of storage space and/or of processing resources to determine whether to dynamically adjust the quantity of reading threads.
