| <div class="block"><code>SequenceFile</code>s are flat files consisting of binary key/value |
| pairs. |
| |
| <p><code>SequenceFile</code> provides <code>SequenceFile.Writer</code>, |
| <code>SequenceFile.Reader</code> and <code>SequenceFile.Sorter</code> classes for writing, |
| reading and sorting respectively.</p> |
| |
| There are three <code>SequenceFile</code> <code>Writer</code>s based on the |
| <code>SequenceFile.CompressionType</code> used to compress key/value pairs: |
| <ol> |
| <li> |
| <code>Writer</code> : Uncompressed records. |
| </li> |
| <li> |
| <code>RecordCompressWriter</code> : Record-compressed files, only compress |
| values. |
| </li> |
| <li> |
| <code>BlockCompressWriter</code> : Block-compressed files, both keys & |
| values are collected in 'blocks' |
| separately and compressed. The size of |
| the 'block' is configurable. |
| </ol> |
| |
| <p>The actual compression algorithm used to compress key and/or values can be |
| specified by using the appropriate <a href="../../../../org/apache/hadoop/io/compress/CompressionCodec.html" title="interface in org.apache.hadoop.io.compress"><code>CompressionCodec</code></a>.</p> |
| |
| <p>The recommended way is to use the static <tt>createWriter</tt> methods |
| provided by the <code>SequenceFile</code> to chose the preferred format.</p> |
| |
| <p>The <code>SequenceFile.Reader</code> acts as the bridge and can read any of the |
| above <code>SequenceFile</code> formats.</p> |
| |
| <h3 id="Formats">SequenceFile Formats</h3> |
| |
| <p>Essentially there are 3 different formats for <code>SequenceFile</code>s |
| depending on the <code>CompressionType</code> specified. All of them share a |
| <a href="#Header">common header</a> described below. |
| |
| <h4 id="Header">SequenceFile Header</h4> |
| <ul> |
| <li> |
| version - 3 bytes of magic header <b>SEQ</b>, followed by 1 byte of actual |
| version number (e.g. SEQ4 or SEQ6) |
| </li> |
| <li> |
| keyClassName -key class |
| </li> |
| <li> |
| valueClassName - value class |
| </li> |
| <li> |
| compression - A boolean which specifies if compression is turned on for |
| keys/values in this file. |
| </li> |
| <li> |
| blockCompression - A boolean which specifies if block-compression is |
| turned on for keys/values in this file. |
| </li> |
| <li> |
| compression codec - <code>CompressionCodec</code> class which is used for |
| compression of keys and/or values (if compression is |
| enabled). |
| </li> |
| <li> |
| metadata - <code>SequenceFile.Metadata</code> for this file. |
| </li> |
| <li> |
| sync - A sync marker to denote end of the header. |
| </li> |
| </ul> |
| |
| <h5>Uncompressed SequenceFile Format</h5> |

| </ul> |
| </li> |
| <li> |
| A sync-marker every block. |
| </li> |
| </ul> |
| |
| <p>The compressed blocks of key lengths and value lengths consist of the |
| actual lengths of individual keys/values encoded in ZeroCompressedInteger |
| format.</p></div> |
