> Take a look at the typical binary string functions and bit string operators that are
implemented in relational database systems (
and and implement the
same for Phoenix in Java following this guide:
> 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.
