-Snappy compressed format description
-Last revised: 2011-10-05
-
-
-This is not a formal specification, but should suffice to explain most
-relevant parts of how the Snappy format works. It is originally based on
-text by Zeev Tarantov.
-
-Snappy is a LZ77-type compressor with a fixed, byte-oriented encoding.
-There is no entropy encoder backend nor framing layer -- the latter is
-assumed to be handled by other parts of the system.
-
-This document only describes the format, not how the Snappy compressor nor
-decompressor actually works. The correctness of the decompressor should not
-depend on implementation details of the compressor, and vice versa.
-
-
-1. Preamble
-
-The stream starts with the uncompressed length (up to a maximum of 2^32 - 1),
-stored as a little-endian varint. Varints consist of a series of bytes,
-where the lower 7 bits are data and the upper bit is set iff there are
-more bytes to be read. In other words, an uncompressed length of 64 would
-be stored as 0x40, and an uncompressed length of 2097150 (0x1FFFFE)
-would be stored as 0xFE 0xFF 0x7F.
-
-
-2. The compressed stream itself
-
-There are two types of elements in a Snappy stream: Literals and
-copies (backreferences). There is no restriction on the order of elements,
-except that the stream naturally cannot start with a copy. (Having
-two literals in a row is never optimal from a compression point of
-view, but nevertheless fully permitted.) Each element starts with a tag byte,
-and the lower two bits of this tag byte signal what type of element will
-follow:
-
- 00: Literal
- 01: Copy with 1-byte offset
- 10: Copy with 2-byte offset
- 11: Copy with 4-byte offset
-
-The interpretation of the upper six bits are element-dependent.
-
-
-2.1. Literals (00)
-
-Literals are uncompressed data stored directly in the byte stream.
-The literal length is stored differently depending on the length
-of the literal:
-
- - For literals up to and including 60 bytes in length, the upper
- six bits of the tag byte contain (len-1). The literal follows
- immediately thereafter in the bytestream.
- - For longer literals, the (len-1) value is stored after the tag byte,
- little-endian. The upper six bits of the tag byte describe how
- many bytes are used for the length; 60, 61, 62 or 63 for
- 1-4 bytes, respectively. The literal itself follows after the
- length.
-
-
-2.2. Copies
-
-Copies are references back into previous decompressed data, telling
-the decompressor to reuse data it has previously decoded.
-They encode two values: The _offset_, saying how many bytes back
-from the current position to read, and the _length_, how many bytes
-to copy. Offsets of zero can be encoded, but are not legal;
-similarly, it is possible to encode backreferences that would
-go past the end of the block (offset > current decompressed position),
-which is also nonsensical and thus not allowed.
-
-As in most LZ77-based compressors, the length can be larger than the offset,
-yielding a form of run-length encoding (RLE). For instance,
-"xababab" could be encoded as
-
- <literal: "xab"> <copy: offset=2 length=4>
-
-Note that since the current Snappy compressor works in 32 kB
-blocks and does not do matching across blocks, it will never produce
-a bitstream with offsets larger than about 32768. However, the
-decompressor should not rely on this, as it may change in the future.
-
-There are several different kinds of copy elements, depending on
-the amount of bytes to be copied (length), and how far back the
-data to be copied is (offset).
-
-
-2.2.1. Copy with 1-byte offset (01)
-
-These elements can encode lengths between [4..11] bytes and offsets
-between [0..2047] bytes. (len-4) occupies three bits and is stored
-in bits [2..4] of the tag byte. The offset occupies 11 bits, of which the
-upper three are stored in the upper three bits ([5..7]) of the tag byte,
-and the lower eight are stored in a byte following the tag byte.
-
-
-2.2.2. Copy with 2-byte offset (10)
-
-These elements can encode lengths between [1..64] and offsets from
-[0..65535]. (len-1) occupies six bits and is stored in the upper
-six bits ([2..7]) of the tag byte. The offset is stored as a
-little-endian 16-bit integer in the two bytes following the tag byte.
-
-
-2.2.3. Copy with 4-byte offset (11)
-
-These are like the copies with 2-byte offsets (see previous subsection),
-except that the offset is stored as a 32-bit integer instead of a
-16-bit integer (and thus will occupy four bytes).

-Snappy framing format description
-Last revised: 2013-10-25
-
-This format decribes a framing format for Snappy, allowing compressing to
-files or streams that can then more easily be decompressed without having
-to hold the entire stream in memory. It also provides data checksums to
-help verify integrity. It does not provide metadata checksums, so it does
-not protect against e.g. all forms of truncations.
-
-Implementation of the framing format is optional for Snappy compressors and
-decompressor; it is not part of the Snappy core specification.
-
-
-1. General structure
-
-The file consists solely of chunks, lying back-to-back with no padding
-in between. Each chunk consists first a single byte of chunk identifier,
-then a three-byte little-endian length of the chunk in bytes (from 0 to
-16777215, inclusive), and then the data if any. The four bytes of chunk
-header is not counted in the data length.
-
-The different chunk types are listed below. The first chunk must always
-be the stream identifier chunk (see section 4.1, below). The stream
-ends when the file ends -- there is no explicit end-of-file marker.
-
-
-2. File type identification
-
-The following identifiers for this format are recommended where appropriate.
-However, note that none have been registered officially, so this is only to
-be taken as a guideline. We use "Snappy framed" to distinguish between this
-format and raw Snappy data.
-
- File extension: .sz
- MIME type: application/x-snappy-framed
- HTTP Content-Encoding: x-snappy-framed
-
-
-3. Checksum format
-
-Some chunks have data protected by a checksum (the ones that do will say so
-explicitly). The checksums are always masked CRC-32Cs.
-
-A description of CRC-32C can be found in RFC 3720, section 12.1, with
-examples in section B.4.
-
-Checksums are not stored directly, but masked, as checksumming data and
-then its own checksum can be problematic. The masking is the same as used
-in Apache Hadoop: Rotate the checksum by 15 bits, then add the constant
-0xa282ead8 (using wraparound as normal for unsigned integers). This is
-equivalent to the following C code:
-
- uint32_t mask_checksum(uint32_t x) {
- return ((x >> 15) | (x << 17)) + 0xa282ead8;
- }
-
-Note that the masking is reversible.
-
-The checksum is always stored as a four bytes long integer, in little-endian.
-
-
-4. Chunk types
-
-The currently supported chunk types are described below. The list may
-be extended in the future.
-
-
-4.1. Stream identifier (chunk type 0xff)
-
-The stream identifier is always the first element in the stream.
-It is exactly six bytes long and contains "sNaPpY" in ASCII. This means that
-a valid Snappy framed stream always starts with the bytes
-
- 0xff 0x06 0x00 0x00 0x73 0x4e 0x61 0x50 0x70 0x59
-
-The stream identifier chunk can come multiple times in the stream besides
-the first; if such a chunk shows up, it should simply be ignored, assuming
-it has the right length and contents. This allows for easy concatenation of
-compressed files without the need for re-framing.
-
-
-4.2. Compressed data (chunk type 0x00)
-
-Compressed data chunks contain a normal Snappy compressed bitstream;
-see the compressed format specification. The compressed data is preceded by
-the CRC-32C (see section 3) of the _uncompressed_ data.
-
-Note that the data portion of the chunk, i.e., the compressed contents,
-can be at most 16777211 bytes (2^24 - 1, minus the checksum).
-However, we place an additional restriction that the uncompressed data
-in a chunk must be no longer than 65536 bytes. This allows consumers to
-easily use small fixed-size buffers.
-
-
-4.3. Uncompressed data (chunk type 0x01)
-
-Uncompressed data chunks allow a compressor to send uncompressed,
-raw data; this is useful if, for instance, uncompressible or
-near-incompressible data is detected, and faster decompression is desired.
-
-As in the compressed chunks, the data is preceded by its own masked
-CRC-32C (see section 3).
-
-An uncompressed data chunk, like compressed data chunks, should contain
-no more than 65536 data bytes, so the maximum legal chunk length with the
-checksum is 65540.
-
-
-4.4. Padding (chunk type 0xfe)
-
-Padding chunks allow a compressor to increase the size of the data stream
-so that it complies with external demands, e.g. that the total number of
-bytes is a multiple of some value.
-
-All bytes of the padding chunk, except the chunk byte itself and the length,
-should be zero, but decompressors must not try to interpret or verify the
-padding data in any way.
-
-
-4.5. Reserved unskippable chunks (chunk types 0x02-0x7f)
-
-These are reserved for future expansion. A decoder that sees such a chunk
-should immediately return an error, as it must assume it cannot decode the
-stream correctly.
-
-Future versions of this specification may define meanings for these chunks.
-
-
-4.6. Reserved skippable chunks (chunk types 0x80-0xfd)
-
-These are also reserved for future expansion, but unlike the chunks
-described in 4.5, a decoder seeing these must skip them and continue
-decoding.
-
-Future versions of this specification may define meanings for these chunks.
