James Taylor updated PHOENIX-1665:
----------------------------------
Description:
Take a look at the typical ARRAY built-in functions that are implemented in
relational database systems
(http://www.postgresql.org/docs/9.2/static/functions-array.html) and implement
the same for Phoenix in Java following this guide:
http://phoenix-hbase.blogspot.com/2013/04/how-to-add-your-own-built-in-function.html
Examples of missing functions include ARRAY_APPEND, ARRAY_FILL, ARRAY_PREPEND,
etc.
was:
Take a look at the typical binary string functions and bit string operators
that are implemented in relational database systems
(http://www.postgresql.org/docs/8.1/static/functions-binarystring.html and
http://www.postgresql.org/docs/8.1/static/functions-bitstring.html) and
implement the same for Phoenix in Java following this guide:
http://phoenix-hbase.blogspot.com/2013/04/how-to-add-your-own-built-in-function.html
Examples of missing functions include GET_BYTE, SET_BYTE, GET_BIT, SET_BIT, etc
and missing operators include &, |, #, ~, <<, and >>. As a guide, examine how
ROUND is implemented in Phoenix as an abstract function with concrete functions
per type: long, decimal, and date/time types, as many of the existing built-in
functions are already defined but are not applicable for binary types.
