Quote: files of integers should always be stored compressed; faster access; use variable-bit compression for files larger than 100 Mbyte

Quotation Skeleton

We describe several different methods of storing integers … reasonable compression and fast retrieval of numeric data. … disk space requirements, minimize main memory use, and--because … we consider the bit-wise Elias gamma and delta … [ref], and parameterized Golomb codes [ref]; … we evaluate byte-wise storage using standard four-byte integers … [p. 200] For sequential stream retrieval, applying a selected … over … uncompressed 32-bit integers. For smaller files, variable-byte schemes … [p. 201] [and] larger data sets, a carefully selected … variable-byte schemes work well for random access to … [more than a few megabytes in size]. … given that addition of compression to read or … [files of integers] should always be stored compressed.   Google-1   Google-2
