> Add column-aliasing capability to hbase-client
> ----------------------------------------------
>
> Key: HBASE-17257
> URL: https://issues.apache.org/jira/browse/HBASE-17257
> Project: HBase
> Issue Type: New Feature
> Components: Client
> Affects Versions: 2.0.0
> Reporter: Daniel Vimont
> Assignee: Daniel Vimont
> Labels: features
> Attachments: HBASE-17257.patch
>
>
> Column aliasing will provide the option for a 1, 2, or 4 byte alias value to
> be stored in each cell of an "alias enabled" column-family, in place of the
> full-length column-qualifier. Aliasing is intended to operate completely
> invisibly to the end-user developer, with absolutely no "awareness" of
> aliasing required to be coded into a front-end application. No new public
> hbase-client interfaces are to be introduced, and only a few new public
> methods should need to be added to existing interfaces, primarily to allow an
> administrator to designate that a new column-family is to be alias-enabled by
> setting its aliasSize attribute to 1, 2, or 4.
> To facilitate such functionality, new subclasses of HTable,
> BufferedMutatorImpl, and HTableMultiplexer are to be provided. The overriding
> methods of these new subclasses will invoke methods of the new AliasManager
> class to facilitate qualifier-to-alias conversions (for user-submitted Gets,
> Scans, and Mutations) and alias-to-qualifier conversions (for Results
> returned from HBase) for any Table that has one or more alias-enabled column
> families. All conversion logic will be encapsulated in the new AliasManager
> class, and all qualifier-to-alias mappings will be persisted in a new
> aliasMappingTable in a new, reserved namespace.
> An informal polling of HBase users at HBaseCon East and at the
> Strata/Hadoop-World conference in Sept. 2016 showed that Column Aliasing
> could be a popular enhancement to standard HBase functionality, due to the
> fact that full column-qualifiers are stored in each cell, and reducing this
> qualifier storage requirement down to 1, 2, or 4 bytes per cell could prove
> beneficial in terms of reduced storage and bandwidth needs. Aliasing is
> intended chiefly for column-families which are of the "narrow and tall"
> variety (i.e., that are designed to use relatively few distinct
> column-qualifiers throughout a large number of rows, throughout the lifespan
> of the column-family). A column-family that is set up with an alias-size of 1
> byte can contain up to 255 unique column-qualifiers; a 2 byte alias-size
> allows for up to 65,535 unique column-qualifiers; and a 4 byte alias-size
> allows for up to 4,294,967,295 unique column-qualifiers.
> Fuller specifications will be entered into the comments section below. Note
> that it may well not be viable to add aliasing support in the new "async"
> classes that appear to be currently under development.
