[jira] [Updated] (HBASE-8201) Implement serialization strategies

["Nick Dimiduk (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-8201?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Nick Dimiduk updated HBASE-8201:
--------------------------------

    Attachment: 0001-HBASE-8201-OrderedBytes-provides-order-preserving-se.patch

WIP Commit. OrderedBytes provides a serialization format in which the resulting byte[] retains the same sort order as the natural types. Serialized formats can be inspected and decoded without forward knowledge of their content. Implementations are provided for Numeric values with up to 64-bits of precision, Strings, and byte[].

The encoding format is modeled after the SQLite4 key encoding format. See http://sqlite.org/src4/doc/trunk/www/key_encoding.wiki for details.
    
TODOs include:
 - descending sort order
 - encoding and decoding sequences of values ("compound rowkey")
 - bounds/error checking with String encoding
 - support for "mid" blob encoding and decoding, allowing byte[] to be used in the middle of compound keys.
 - utilities for counting, skipping encoded values on a ByteBuffer
 - consider using BigInteger/BigDecimal to allow for arbitrary size and precision numerics.
