Claim 31:
32. A method for hardware-implemented file readout, comprising:
accessing a file using multiple hardware-implemented column readers, wherein the file comprises multiple records, wherein the file is stored in a columnar format having multiple columns, each column storing (i) compressed values and (ii) corresponding compressed structure information that associates the values in the column to the records;
assigning each column reader to a respective selected column, and reading and decompressing both the values and the structure information from at least a portion of the selected column; and
using a hardware-implemented record reconstructor, aligning the column readers to one another so as to provide respective outputs that are aligned to the records of the file, reconstructing one or more records of the file from at least portions of the columns that are read by the aligned column readers, and outputting the reconstructed records.
